The present application pertains to portable smoking cessation devices, in general, and to a modular portable smoking cessation device with authentication, encryption, and lock, in particular.
Countless smokers have adopted some form of portable smoking cessation (PSC) device to promote cessation of tobacco product smoking. Typically, battery-operated PSC devices include a device body, a battery attached to the device body, and a reservoir of liquid, often flavored, that contains an active ingredient, such as nicotine. The reservoir also can be called a “pod” or cartridge, and the liquid can be known as “e-liquid” or “juice.” By inhaling through the PSC device, the e-liquid can be wicked into an electric firing chamber that produces a smoke-like vapor for inhalation. This activity can be called “vaping.”
Certain users of such devices may have no intention of ceasing to use tobacco or nicotine products, and the term “PSC device” as used herein is broad enough to cover device or components disclosed herein for vaping or inhalation of various chemicals whether or not the user intends to cease his or her behavior in the future.
Although vaping is less hazardous than tobacco smoking, recent events indicate that e-liquid material can be inauthentic, and PSC devices or their components can be counterfeited or modified, such that some users suffer pulmonary insults and even death. Furthermore, vaping has become widespread among the young, including high school and middle school children. Indeed, in a press conference on Dec. 18, 2018, the United States Surgeon General, Jerome M. Adams officially declared the use of e-cigarettes among youth to be an “epidemic.” www.safetyandhealthmagazine.com/articles/17921-number-of-teens-vaping-hits-record-high-survey-shows (Jan. 10, 2019), accessed Oct. 17, 2019.
It has become a priority to prevent juveniles from purchasing PSC devices and from using imitation e-liquid materials. There can be difficulties even for age-appropriate users with current PSC devices. For example, the amount and characteristics of e-liquid used cannot be adequate controlled, if at all. Data pertaining to device and e-liquid use cannot be accurately tracked and analyzed. Device and e-liquid counterfeiting is common. The device is unlikely to be intelligent, that is, it is difficult, if not impossible, to track e-liquid use and characteristics, as well as PSC device identification and operational data. Moreover, e-liquid leakage is common. Typically, the user needs to manually adjust various options. Also, vapor and e-liquid information cannot be collected, so the equipment cannot engage in intelligent analysis and operation. In addition, the structure of an e-liquid cartridge may allow for occasional e-liquid leakage from time to time. Moreover, the types of vapors and e-liquids can be complex complicated. Currently, e-liquids cannot be traced back to the source, cannot carry out batch management, and cannot provide accurate device and e-liquid usage information, including device statistics.
What is needed is a PSC device that makes difficult counterfeiting and illicit device use and can identify and use authentic e-liquid.
The invention provides a personal smoking cessation (PSC) device which makes difficult counterfeiting and illicit device use, which can identify and use authentic e-liquid, which can be electronically locked by touching a contact, and which can provide data and feedback to the user regarding usage statistics.
The invention also provides a PSC device, including an e-liquid cartridge, an EEPROM disposed within the e-liquid cartridge, and a host body communicatingly coupled to the EEPROM. The EEPROM within the e-liquid cartridge communicates with the host body. The EEPROM is a data encryption EEPROM, in which data to the EEPROM is encrypted, and data from the EEPROM is decrypted. The EEPROM is an authenticating EEPROM, in which a user is authenticated as an authorized user. In embodiments, the authenticating EEPROM is a multi-factor authenticating EEPROM, in which the user supplies a plurality of authenticating factors so that the user is authenticated as an authorized user. The PSC device includes a touch-sensitive electronic lock. In embodiments, the electronic lock is disposed within the host body. In embodiments, the electronic lock is coupled with a female USB connector. The electronic lock can be actuated by touching the female USB connector. The e-liquid cartridge is coupled to the host body with a first preselected electromechanical connector, which is a USB Type C electromechanical connector mechanically and electrically coupling the e-liquid cartridge with the host body. In embodiments, the host body further includes a radio transceiver configured to exchange data with a communication device external to the PSC device. In embodiments, the host body is configured to receive a rechargeable battery, a replaceable battery, or a rechargeable, replaceable battery.
The invention further provides a Personal Smoking Cessation (PSC) device, which includes an e-liquid cartridge storing a preselected fluid to be vaporized and a vaporization element configured to vaporize the preselected fluid. Also included is an EEPROM within the e-liquid cartridge, in which the EEPROM has a universally unique identifier (UUID) stored therein, in which the EEPROM facilitates authentication of a user, the e-liquid cartridge, and the preselected fluid, and in which the EEPROM facilitates encryption of received data and decryption of transmitted data. The device additionally includes a host body with a first female USB-C electromechanical connector communicatingly coupled to the EEPROM having a first male USB-C electromechanical connector. The first male and a first female USB-C electromechanical connectors form positive mechanical and electrical connections between the EEPROM and the host body. The host body exchanges data with the EEPROM. The host body includes an electronic lock. In embodiments, the electronic lock reversibly locks the EEPROM, and the electronic lock is operably coupled to a second female USB-C electromechnical connector. In embodiments, the PSC device further includes a Bluetooth radio transceiver coupled to the EEPROM, in which the Bluetooth radio transceiver communicates data between the PSC device and a second Bluetooth transceiver disposed in an external communication device.
These and other advantages of the present invention will be further understood and appreciated by those skilled in the art by reference to the following written specifications, claims and appended drawings.
In the FIGURES, which are not drawn to scale, like numerals refer to like features throughout the description. The following description is not to be taken in a limiting sense but is made merely for describing the general principles of the invention. Preferred embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings, in which:
Some embodiments are described in detail with reference to the related drawings. Additional embodiments, features, and/or advantages will become apparent from the ensuing description or may be learned by practicing the invention.
The present embodiments provide a personal smoking cessation (PSC) device that employs authentication, encryption, or locking, or a combination, to make difficult counterfeiting and illicit use, and which can be finely controlled as to its operational behavior, and which can provide helpful usage statistics. At present, there is no e-liquid cartridge having built-in encryption or authentication device elements. The present invention can provide a meaningful solution to the counterfeit problem, and which can be controlled as to its operational behavior, and which can provide helpful usage statistics.
As used herein, identification is the claiming of an identity, whereas authentication is the act of verifying or proving the claimed identity. In authorization, a system entity or actor has been granted the right, permission, or capability to access a system resource. Encryption is the cryptographic transformation of data (called “plaintext”) into a form (called “ciphertext”) that conceals the data's original meaning to prevent it from being known or used. If the transformation is reversible, the corresponding reversal process is called “decryption,” which is a transformation that restores encrypted data to its original state.

Mouth cover 210 can be made of a molded rigid or semi-rigid food grade plastic, such as, without limitation, polypropylene (PP) or PCTG (Poly-Cyclohexylenedimethylene Terephthalate Glycol). PCTG is a food-grade thermoplastic glycol-modified terephthalate copolyester creating rigid or semi-rigid structures. PCTG has anti-corrosion, anti-leach properties, is recyclable and biodegradable, and does not emit the toxin bisphenol A (BPA). PCTG offers toughness, impact strength, and clarity. PP may be the safest of all plastics, and is a robust plastic that is heat resistant. Because of its high heat tolerance, PP is unlikely to leach even when exposed to warm or hot water and is approved for use with food and beverage storage E-liquid cartridge 220 also can be made of, without limitation, PCTG. Cartridge connector 230 can be a USB type-C (USB-C) male connector, which can form an electromechanical connection with a corresponding female USB-C connector (not shown) in host body 240, can facilitate an exchange of data between e-liquid cartridge 220 and host body 240, and can provide electrical power to e-liquid cartridge 220. The mated USB-C connector also provides mechanical mating and stability with the USB-C junction.
Host body 240 can be a shell, made of sturdy material, such as plastic, metal, or a composite material. In embodiments, body 240 can be CNC aluminum. Body 240 can be formed to provide battery compartment 250 and to receive motherboard 270. Battery compartment 250 can hold in place battery 260, which can be a rechargeable lithium-ion battery with a nominal voltage of about 3.7V and an energy capacity of about 550 mAh. A battery of another type and electrical characteristics also may be used, including battery 260, which may be rechargeable, replaceable, or both. Attached to battery compartment 250 can be motherboard 270. Motherboard 270 can hold operational components and connectors for PSC device 200, for example, negative pressure switch 280, upper body connector 290, and lower body connector 295. Negative pressure switch 280 can be an airflow sensor, which actuates heating in cartridge 220 when the negative pressure associated with a user's inhalation is reduced to a preset value. Upper body connector 290 can provide a secure mechanical receptacle for cartridge connector 230, as well as provide data exchange and electrical power between e-liquid cartridge 220 and motherboard 270. In embodiments, upper body connector 290 can be physically compatible with e-liquid cartridge connector 230 and may be a USB-C female connector. In use, the physical connection between connector 230 and mating connector 290 can positively and securely hold cartridge 220 in body 240. In addition, motherboard 270 may be electrically coupled to lower body connector 295. Lower body connector 295 may be a USB-C female connector for providing a streamlined physical appearance, while allowing communications with an external device, although a USB-C male connector also may be used. In general, data and electrical connections may exist between e-liquid cartridge 220 and lower body connector 295. Motherboard 270 may contain several operational circuits (not shown), which may perform specific functions to facilitate operation of PSC device 200, for example, without limitation, power adjustment, reverse polarity protection, earth leakage protection, intelligent power management, Bluetooth communication, e-liquid cartridge intelligent chip management, timing, temperature management, resistance adjustment, preheating, overheat prevention, touch detection, and PSC electronic lock. Motherboard 270 may be composed of a single layer or multiple layers or comprise multiple stacked boards. Electrically coupled to motherboard 270 may be work indicator light 245, a LED which provides a physical indication of the operational state of PSC device 200, for example, charge state and power status (on/off).

Mouth cover 305 can be formed with vapor passage 310 therethrough, which allows vapor generated through the operation of heating element 330 to be received by an inhaling user. To prevent leakage of e-liquid from the top of e-liquid reservoir, cartridge sealing cover 315 can be securely fastened to the proximal end of reservoir 320. To allow for compact design, flue or vapor tube 325 can pass through reservoir 320 and be coupled to vapor passage 310 of mouth cover 305. At the distal end of vapor tube 325 can be an enlarged portion 380, which can be configured to receive heating element 330. As heating element 330 operates, e-liquid (not shown) from e-liquid reservoir 320 is vaporized and travels through vapor tube 325 to vapor passage 310. In embodiments, heating element 330 can be a hybrid ceramic heating element in which a ceramic support may be wrapped by Type 316 stainless steel.
Furthermore, heating element 330 may be a hybrid heating element, which can have organic cotton disposed within the coils of heating element 330. Atomization chamber bracket 335 can stabilize vapor tube 325 and heating element 330 when assembled. To mitigate the effects of heating on structures distal to atomization chamber 335, heating wire insulation 340 can be provided. In embodiments, insulation 340 can be a silica gel. Bracket cover 350 encloses atomization chamber bracket 335 to prevent leakage of e-liquid (not shown). Physically and electrically coupled to atomization chamber bracket 335 can be USB-C male connector 360. USB-C male connector 360 can be used to secure e-liquid cartridge 300 into a USB-C female connector in PSC device host body, as is depicted in
EEPROM 375 can be used to store data regarding, for example, the characteristics of the cartridge, the content of the cartridge, smoking routines of the user, etc. In particular, a non-limiting list of data stored in EEPROM can include: cartridge content; cartridge brand; where cartridge is made; brand flavor; content volume; maximum number of drags or puffs; main ingredient; co-ingredients (up to) 10; solvent used (up to 3 types); product batch number; content viscosity; whether preheating is needed; time delay for preheat; and heating coil type. Cartridge content indicates what the cartridge contains, including, for example, nicotine mixture, a CDB solution, a THC tincture, a cannabis wax, or a preselected medication. Cannabis wax is a form of hash oil concentrate created when a solvent is washed over marijuana plant material.
Cartridge brand indicates which brand of cartridge is being used, which itself provides information about the cartridge, its contents, and the context in which it is used. It can be important to know where the cartridge is made, for example, California or Colorado, etc., for quality control, for supply chain accountability, and for recall purposes. Brand flavor can be useful for identifying ingredients of a particular branded cartridge. Content volume describes how much content is in the cartridge. Typical values may be between about 0.5 ml to about 10 ml maximum volume. In view of the identified cartridge volume, a corresponding maximum number of drags is defined. When the maximum number of drags is reached, the cartridge locks and can no longer be used. In an embodiment, the cartridge is locked between about 350-800 drags, with a typical 1000 drag maximum. In an alternative embodiment, the total time length for vaporization may be used. In this instance, the total time of vaporization before the cartridge locks may be between about 150 seconds to about 2,000 seconds. This feature prevents the cartridge from being refilled, for example, with harmful ingredients, and resold on the black market, and removes the economic benefit of illicit or counterfeit trade. This feature also can be useful in situations in which the content is a controlled (e.g., THC) or potentially hazardous (e.g., nicotine) substance.
It is useful to know the main ingredient of the cartridge content, as well as co-ingredients of the content. Identified can be the ingredient or co-ingredient, its respective volume in milliliters, and the ratio of the co-ingredient mixture. In an embodiment, up to 10 co-ingredients can be identified, measured in milligrams. Up to 3 solvent types also can be stored. A solvent can be used for oily or waxy substances such as, THC and CBD ingredients. Product batch number identifies the particular batch of the product stored in the cartridge which, when accompanied by cartridge content and brand identification can specifically identify the production information of the cartridge. Batch number may be stored in a 32-byte value, producing roughly about 10e+77 unique batch number values. Content viscosity may be stored as a percentage of a known value, for example, between about 0% to about 100%. Content viscosity can be useful to know, for example, for gauging and setting heating and preheating parameters. To that end, it is important to know whether preheating is desired for the content, and if so, the selected time delay and target preheat temperature and resistance values. In order to properly set the parameters needed for heating and preheating, it is necessary to know what type of heating coil is being used, for example, platinum, 316 stainless steel, nickel coated iron, etc. In the cartridge, behavioral data may be stored in the EEPROM, for example, each day may be separated into six (6), four (4) hour intervals, for mapping user behavior of drags and length of intake in each time interval. To accomplish this, the total number of drags in a predefined period are counted, and the total number of seconds of inhalation (in 0.1 s increments) per drag on the cartridge are measured. The data stored maps user behavior of drags and length of intake in each time interval.
Selected personal and usage data can be stored on the cartridge. Personal data can include, for example, user name, smoking history, and user age. The most recent 6 intervals (one day) can be stored on the cartridge. Each day for a total of 180 intervals (30 days) may be transferred to and stored on a memory device in the device body. In turn, this data can be transferred to and stored on a cloud. Usage data also may be collected and stored on the cloud, such as the number of drags per cartridge use, the average time length for drags, total number of drags, and the time interval for the drags. Transfer from cartridge to body may be accomplished by a USB-C connection between device and body, or by a short range wireless connection. Transfer from body to cloud may be accomplished by coupling a smartphone to the device body and transmitting the data from the body to the cloud via the smartphone. Alternatively, the body may contain a cellular or long range radio therein, which may use 4G, 5G, or 6G wireless capability to connect directly between body and the cloud. Data stored in the cloud which can be shared with a PSC device may include cartridge activation status, cartridge disable command, when set or disable only by batch at daily maximum count, and cartridge daily maximum setting. These three data currently are determined per batch of cartridges, but not for a single cartridge.
Data sampling can be initiated by the microphone, which can be a negative pressure sensor. For example, when a drag is initiated, a negative pressure is sensed by the microphone. When the microphone is activated continuously for more than 500 milliseconds, the count of the number of drags can be incremented by one and total time for drag can be incremented by the length of the drag. This data can be written into firmware storage, as well as cartridge memory. Moreover, the number of seconds that the microphone is activated can be measured in 0.1 second intervals. Then, the total number of seconds of activation can be recorded and written in firmware storage as an updated total number of seconds, and also writes this data into cartridge memory. The data record can be separated by time slots of 6 intervals of 4 hours. Each interval may have an updated total number of drags, and total amount of time in 0.1 seconds resolution. A cartridge only may have the record of the most recent 6 intervals with the others being recorded in the device body. PSC device can record up to 180 time intervals of data, including the total time of drags counted and the time for each drag. Data can be stored when a cartridge is connected, and whenever a user interacts with the PSC device. In an embodiment, data can be transferred between the cartridge EEPROM memory and the body using the IIC (I2C) protocol.
In embodiments, host body 700 can be composed of internal assembly 710, which can be inserted and secured into body shell 760. Internal assembly 710 includes, inter alia, battery compartment 720, rechargeable battery 730, and motherboard 740, which is coupled to Bluetooth® radio module 750. IEEE 802.15.1 (or Bluetooth®) radio module 750 may be replaced by a radio module employing, without limitation, Bluetooth® Low Energy (BLE); Z-Wave; 6LoWPAN; Thread Protocol; Near-Field Communication (NFC) and HF RFID; IEEE Std. 802.15.4 (ZigBee®); IEEE Std. 802.15.6 (wireless body area network—WBAN) protocols; UWB; or WiGig™ (e.g., IEEE Std. 802.11ad), although other short-range communications protocols may be used.

It is desirable to prevent minors or unauthorized parties from using PSC device 1100. A user (not shown) can employ identification and authentication, in order to receive authorization to use PSC device 1100. Initially, the user registers by creating an account on-line through an external communication device such as, without limitation, PC or smartphone 1125, or other internet enabled device. During the registration process, the user supplies a unique ID (e.g., unique username, e-mail address, or 10-digit phone number) and a corresponding authenticating password. This information can be transmitted to host server 1175 during identification and activation, along with other information which may include the serial number of the PSC device 1100 or serial numbers/codes associated with e-cartridges 1120 that are in the possession of the user. Thus, the registered user and his or her e-cartridges 1120 will be associated with the PSC device 1100 and no one else will be able to use the PSC device 1100 or cartridges 1120. In this way, host activation ID authentication can effectively prevent the use of PSC device 1100 by minors. In addition, to ensure that the PSC device 1100 confirms the identity and age of the user, a photo identification may be required, which may be a government photo identification, including birthdate, among other things. This ID may be sent to a server. Acceptable forms of government photo identification include, for example, passports, Personal Identity Verification (PIV) cards, and drivers' licenses, Military ID, Permanent Resident Visa/Green Card, other Government-issued ID, etc. Government-issued ID is unlikely to be counterfeited. Multi-factor authentication also may be used. Multi-factor authentication is an authentication technique that requires users to provide multiple forms of identification when logging in. Each PSC device 1100 can have stored within it a unique, unalterable 128-bit identifier, serial number, or both, that can be associated with the credentials provided by a particular user, including username and password. The user may then be authenticated locally to the mobile device by entering a PSC-related serial number, passcode or PIN, or by using mobile device-level biometrics to be able to use the stored credentials. An authorized user can be issued digital credentials that are stored securely on mobile device 1125. Mobile devices 1125 include without limitation, smart mobile phones, tablets, and smart watches. Once an account has been created and the credentials of the user have been approved, the user can be authorized to operate PSC device 1100. If a user is leaving the vicinity of their PSC device 1100, they can lock the device by tapping on the base of PSC device 1100, on the lower body USB-C connector. Alternately, PSC device 1100 may be programmed to affect a lock-out, for example, if the user has been away from their PSC device 1100 and a predetermined amount of time has elapsed without use, or if a user has made a predetermined number of failed authentication attempts. Mobile device 1125, properly authenticated, may be used to observe or change data stored in the EEPROM of device 1100, except for the unalterable, universally unique ID (UUID) also stored in the EEPROM. In addition, mobile device 1125 also may be associated with a serial number, which also may be used for multi-factor authentication.
Through its registration with server 1175, PSC device 1100, is authorized only for a particular user. This may be particularly useful when the PSC dispenses prescription drugs. It may be used only after activation from user's smartphone 1125 or other smart device, or when “unlocked” by a successful series of taps on the lower body connector. Alternatively, a particular group of users may be authorized. Likewise the e-liquid cartridge 1120 also has a unique code or serial number, and may be authorized for use only with the particular PSC device 1100, through registration after purchasing, since smartphone 1125 or other smart device associated with PSC device 1100 will know what e-liquid cartridges 1120 are valid for PSC device 1100 through registration. Thus, PSC device 1100 alone or through communication with smartphone 1125 or other smart device, will only work with predetermined, registered e-liquid cartridges 1120. This prevents third party counterfeit or contraband e-liquid cartridges 1120 from working in PSC device 1100, since the third parties do not know the encryption algorithms used. PSC device 1100 security can prevent users from swapping e-liquid cartridges 1120 to others that may not be authorized (such as minors) or that may have physical issues with the e-liquid cartridges in question.
Moreover, circuit board 375 and motherboard 270 may contain sensors, memory, and variable circuits, connected to smartphone 1125 or other smart device wirelessly (such as Bluetooth or cellular protocols) or by other means. Therefore, the user, through smartphone 1125 app, may control the wattage and time of atomization with the heating elements, thus controlling the amount of chemicals inhaled. Statistics such as overall usage, chemicals inhaled, trends (increasing or decreasing use) and other metrics may be shown on the smart phone or other smart device. E-liquid cartridge 1120 may also contain information indicating its manufacturer, the type of e-liquid it contains, and its current level, as well as other statistics, such as how often it has been used. Such sensor readings, statistics and other data may be uploaded to the cloud 1150 via connected smartphone 1125 or other smart device. Should a PSC device 1100 become lost or stolen, the user simply logs into their account and reports the device missing to the host server 1175. The next time an attempt is made to register device 1100 with host sever 1175, it may be deactivated and become non-functional. Thus, though registration of either or both the e-liquid cartridge 1120 and device 1100 body with central host server 1175, unauthorized use of e-cartridges 1120 and devices 1100 can be prevented. This will greatly improve the safety of devices 1100 and reduce knock-off, and potentially harmful, third party cartridges 1120.

In certain embodiments, such as for ODM distribution, a business-to-business buyer, which typically is not an end user, will pre-fill an e-liquid cartridge with e-liquid, seal the cartridges, and re-sell them as the buyer's brand. A suitable e-liquid may be, without limitation, nicotine, CBD oil, THC oil, or an oral respiratory inhalant, such as, without limitation, albuterol or a corticosteroid. Similarly, PSC device can be sold as an independent carrier brand to other brand owners as a vaporizer and may be sold in a retail website, retail chain, online or in physical stores. E-liquid cartridge can be sold to authorized brands as ODM product. However, each e-liquid cartridge can be assigned an authorized ID code, which may be a unique identification (UID) or a universally unique identification (UUID) in advance for different customers. In embodiments, a unique 128-bit number can be assigned to respective e-liquid cartridge. Each e-liquid cartridge may require an authorized ID code to work with the particular PSC device.
By operation of air pressure sensor 1365, e-liquid atomization occurs in chamber 1320, and the selected vapor enters mouth cover 1305. Also disposed in host body shell 1330 can be main PCB 1365 and Bluetooth® PCB 1370. Main PCB 1370 contains functional elements to enhance the operation of PSC device 1300 including, without limitation, atomization, measuring of PSC temperature data, analyzing and controlling temperature, identification of e-liquid boiling points, power and charging management, and touch detection. Bluetooth® PCB chip 1375 supports and performs Bluetooth® functions to permit and facilitate Bluetooth®-based communications. A suitable Bluetooth® function chip may be an ATB1103 BLE SOC chip.

USB-C is an industry-standard connector for transmitting both data and power on a single cable. USB-C allows for a secure connection between the cartridge and the host body. In addition, a USB-C connector, typically female, may be used as an electronic lock for the host body. The USB-C connector can bidirectionally transfer power between host body printed circuit board (motherboard) and e-liquid cartridge printed circuit board. USB-C connectors are not the only type of physical connector that can be used. Although USB-C connector technology is employed herein, also suitable may be micro-USB, mini-USB, USB-A, USB-B, Lightning (Apple), DisplayPort, PCI-Express, Thunderbolt (Intel), at least 5 spring-loaded connectors (pogo pins), a Firewire (IEEE 1394) connector, and a modular jack connector (e.g., RJ11, RJ45, T568), among other possible wired connectors. A USB-C connector is capable of supporting popular high-bandwidth protocols such as, without limitation, USB 2.x, 3.x, and 4.x, Thunderbolt 3, Lightning, and DisplayPort protocols.
In some embodiments, a short-range wireless protocol may be used to communicate data between cartridge 410 and body 420 including, without limitation, Bluetooth®; Near-Field Communication (NFC); High Frequency RFID (HF RFID); Ultrawide bandwidth (UWB); or other short-range low-power wireless communication protocol. Such a wireless communication link may be used to obviate a physical connection between cartridge 410 and body 420.
As illustrated in
In embodiments, EEPROM 1650 can include therein a preprogrammed, globally unique, unalterable 128-bit sequence that can identify essentially every e-liquid cartridge in existence (128-bit ID provides approximately 3.4×10e+38 identifiers). EEPROM 1650 can be used in conjunction with a microcontroller unit (MCU) (1510,
Although many variations of EEPROM encryption can be performed, the present embodiments employ an advanced dynamic transform encryption algorithm. As an example, encrypted data resides in EEPROM and is read. Two keys are used: the dynamic EEPROM UUID key and the “secret” static MCU key. The respective keys are combined to form a third key. AES encryption/decryption can be performed using the third key to reduce the likelihood that the data will be compromised. The third key also may be used by the MCU to decrypt encrypted data, thereby converting the encrypted data into plaintext data. Conversely, as plaintext is received, the dynamic EEPROM UUID key and the “secret” static MCU key are retrieved and combined to form a third key. Note that the data encrypted onto EEPROM can only be decrypted by one particular MCU, which is embedded in a corresponding PSC device.
