1. Field of the Invention
The present invention is generally in the field of communication. More particularly, the present invention relates to identification and authentication.
2. Background Art
Entertainment venues rely upon a limited set of conventional means for managing guest transactions. One such means is the ubiquitous paper ticket; and another such means is the widespread plastic wristband. A paper ticket, for example, may be typically issued to a guest of a movie theater entertainment venue with the expectation that the guest will maintain possession of the paper ticket for the duration of a movie showing. Thus, a movie theater attendant may ask an apparent guest inside the theater for his ticket to verify an entitlement to attendance. In a similar vein, a plastic wristband, for example, may be typically issued to a guest of a music concert entertainment venue with the expectation that the guest will wear the plastic wristband while at the concert to indicate an entitlement. Thus, concert security personnel may observe a guest's wristband before allowing him into a restricted or privileged area, such as a backstage area.
These various conventional means for managing guest transactions have assorted drawbacks. For example, plastic wristbands, if easily transferable, can pass from guest to guest for re-use, often against the policy of an entertainment venue. For example, a first guest may benefit from a wristband inside a music concert, leave the concert, and transfer the wristband to a second guest who enters the concert and benefits from the wristband, without paying the venue's wristband fee. One solution to this exemplary problem is to render such wristbands inoperable or disabled after removal from the first guest, but such a solution requires continuous wearing of the wristband by the first guest, which may lead to discomfort or inconvenience.
Accordingly, there is a need to overcome the drawbacks and deficiencies in the art by offering an improved identification band for association to a wearer.
An identification band with secured association to the wearer, substantially as shown in and/or described in connection with at least one of the figures, and as set forth more completely in the claims.
The features and advantages of the present invention will become more readily apparent to those ordinarily skilled in the art after reviewing the following detailed description and accompanying drawings, wherein:
The present invention is directed to securely associating an identification band to a wearer. Although the invention is described with respect to specific embodiments, the principles of the invention, as defined by the claims appended herein, can obviously be applied beyond the specific embodiments of the invention described herein. Moreover, in the description of the present invention, certain details have been left out in order to not obscure the inventive aspects of the invention. The details left out are within the knowledge of a person of ordinary skill in the art. The drawings in the present application and their accompanying detailed description are directed to merely exemplary embodiments of the invention. To maintain brevity, other embodiments of the invention, which use the principles of the present invention are not specifically described in the present application and are not specifically illustrated by the present drawings.
Identification band 100 is designed in one embodiment as a wristband to be worn on a wrist of the wearer, and may be sized, for example, to fit the wrist of a child or of an adult. In another embodiment, identification band 100 may be designed as a necklace, for example, or another item of adornment instead of as a wristband. Identification band 100 is shown in
Wires 105 and 106 are, in one embodiment, electrically conducting wires that comprise a closed circuit through conductive clasp 108 when conductive clasp 108 is joined, and that form an open circuit when conductive clasp 108 is disconnected. Sentinel circuit 114 is configured to monitor the conductivity of wires 105 and 106, as known in the art, to determine whether conductive clasp 108 is joined or disconnected. In one embodiment, sentinel circuit 114 is additionally configured to detect attempts to splice wires 105 and 106 with an additional wire by monitoring wires 105 and 106 for changes in resistivity. Sentinel circuit 114 thus may thus determine when identification band 100 is attached or removed from a wrist of the wearer, and may also identify attempts to tamper with identification band 100.
Identification band 100 is associated to the wearer by storing a first profile of the wearer in memory 116. When sentinel circuit 114 detects that conductive clasp 108 has been joined (e.g., when the wearer puts identification band 100 on his wrist), identification band 100 examines memory 116 to determine if the first profile has previously been stored. If so, identification band 100 proceeds with an attempt to re-associate to the wearer, as described further below. However, if there is no first profile stored in memory 116, identification band 100 is configured to receive the first profile via first band transceiver 110. In one embodiment, the first profile is a biometric generated from, for example, a fingerprint scanner. The first profile received by first band transceiver 110 during association may be, for example, a digital representation of a fingerprint, or a checksum generated from a fingerprint. In another embodiment, the first profile is generated from a different type of biometric scanner or sensor, such as, for example, an eye scanner or a facial recognition scanner. In further embodiments, the first profile may comprise nonbiometric information, such as a PIN (“Personal Identification Number”) entered on a keypad by the wearer.
After association of the wearer and identification band 100, the wearer may utilize identification band 100 to perform various transactions in the entertainment venue. In one embodiment, first band transceiver 110 is configured to perform entitlement transactions, while second band transceiver 112 is configured to perform identity transactions. In another embodiment, first band transceiver 110 is configured to perform both entitlement and identity transactions, and in such an embodiment second band transceiver 112 may be omitted. Such transactions are depicted as transactions 210 and 220 in
Identification band 100 is re-associated to the wearer by reattaching identification band 100 to a wrist of the wearer. When sentinel circuit 114 detects that conductive clasp 108 has been rejoined, identification band 100 examines memory 116 and determines that the first profile, previously stored, has been invalidated. Identification band 100 thus attempts to receive a second profile via first band transceiver 110. If the second profile uniquely identifies the first profile stored in memory 116, the first profile is validated. For example, in one embodiment the first profile, previously invalidated, is stored in memory 116 as a digital representation of a fingerprint with an invalid flag bit, and the second profile that uniquely identifies the first profile is a matching digital representation of the same fingerprint, generated during the reattachment and re-association. In another embodiment in which there are two wearers (e.g., a group of authorized wearers), the second profile that uniquely identifies the first profile may be a digital representation of a fingerprint of a second wearer who received a second identification band as part of a group purchase transaction with a first wearer (in such an embodiment, the second wearer has taken (either deliberately or inadvertently) identification band 100 from the first wearer, and may utilize identification band 100 because the first and second wearers may each re-associate with identification band 100). After re-association of the wearer and identification band 100, the wearer may resume utilizing identification band 100 to perform various transactions in the entertainment venue.
In one embodiment, during the association described above, the first profile along with a unique band identifier of identification band 100 are stored on a networked server (not shown) of the entertainment venue. Thus the first profile is stored in a second location (i.e. the networked server) in addition to being stored in memory 116. In such an embodiment, during dissociation of identification band 100 from the wearer, the first profile stored in memory 116 may be invalidated by, for example, outright deletion instead of, for example, setting an invalid flag bit. Identification band 100 can thus be subsequently re-associated to the wearer if the second profile and the unique band identifier of identification band 100 uniquely identify (e.g. match) the first profile and unique band identifier previously stored on the networked server of the entertainment venue.
In system 200, identification band 202 has been associated to wearer 204 by storing a first profile of wearer 204 in a memory of identification band 202. Identification band 202 received the first profile via a first band transceiver from first venue transceiver 212, prior to entitlement transaction 210. In one embodiment of the invention, the first profile is a biometric generated from, for example, a fingerprint scanner (not shown) coupled to first venue transceiver 212. The first profile received by the first band transceiver of identification band 202 during association was, for example, a digital representation of a fingerprint, or a checksum generated from a fingerprint. Having been thus associated to wearer 204, identification band 202 can be utilized during entitlement transaction 210.
In one embodiment of the present invention, entitlement transaction 210 is a payment transaction. In another embodiment, entitlement transaction 210 could be another form of entitlement transaction such as, for example, an entitlement transaction wherein identification band 202 operates as a room key, or wherein identification band 202 decrements a multi-day parking ticket or facilitates single-use entrance to an entertainment or sporting event. In one embodiment, the first band transceiver of identification band 202 is implemented as a payment transceiver by utilizing, for example, a MIFARE chip or another short-range, secure transceiver. Thus implemented, wearer 204 can utilize identification band 202 to purchase, for example, refreshments at a concession stand by presenting identification band 202 to first venue transceiver 212, which in this example also comprises a MIFARE chip. First venue transceiver 212 communicates a purchase request to payment server 216 via network 214. In the present embodiment, payment server 216 can look up a payment account in folio database 218 based on the first profile stored in identification band 202, and record the payment transaction in folio database 218, to be later paid by wearer 204. In another embodiment, payment server can, for example, instead make a charge to a credit card based on the first profile stored in identification band 202.
In addition to entitlement transaction 210, wearer 204 may also utilize identification band 202 to engage in identity transaction 220. Identity transaction 220 is not an entitlement transaction characterized by, for example, exercising a right of wearer 204 or making a purchase for wearer 204. Instead, identity transaction 220 is an identity-based or “know-me” transaction characterized by, for example, personalizing an aspect of an entertainment venue for wearer 204, or for collecting data about wearer 204. Identity transaction 220 is thus based, in one embodiment, on the identity of wearer 204, and not on an entitlement of wearer 204. In identity transaction 220, the second band transceiver of identification band 202 is implemented as, for example, an RFID chip, and transmits the name of wearer 204, stored in the memory of identification band 202 with, or in, a first profile, to second venue transceiver 222. Second venue transceiver 222 transmits the name of wearer 204 to know-me server 224 via network 214, and know-me server 224 may complete identity transaction 220 by performing several exemplary functions with the name of wearer 204.
In one such exemplary function, know-me server 224 transmits an identifier of wearer 204 such as the name of wearer 204 to statistics database 226, a collection of statistical data, to complete identity transaction 220. In particular, in an entertainment venue having a queue for a rollercoaster ride, second venue transceiver 222 can gather the identities (e.g. names) of guests in the queue, including wearer 204. Thus, statistical data about which guests waited for the ride, and how long each guest waited for the ride, can be gathered by statistics database 226. In a second exemplary function, know-me server 224 can transmit an identifier (e.g. name) of wearer 204 to earpiece radio 228 via network 214, and earpiece radio 228 can transmit the identifier of wearer 204 to actor 206 via wireless earpiece 208, to complete identity transaction 220. Actor 206 can be, for example, an actor playing a character in a theme park. From earpiece 208, actor 206 can unobtrusively learn, for example, the name of wearer 204, and can thus interact with wearer 204 in a more personable or entertaining manner.
In step 310 of flowchart 300, an identification band, for example identification band 202 in
In step 312 of flowchart 300, the identification band determines whether a first profile is stored in the memory. Because the identification band has not previously been associated with a wearer, a first profile is not so stored, and the wearer must provide a first profile (e.g., present a biometric such as a fingerprint to a scanner, or enter a PIN on a keypad) in step 314 of flowchart 300. The wearer thus provides a first profile that is stored in the memory of the identification band after being transmitted to the identification band by a first venue transceiver corresponding, for example, to first venue transceiver 212. The identification band is thereby associated to the wearer, and the identification band can thus be utilized to complete the entitlement transaction in step 316.
In step 318 of flowchart 300, after associating the identification band and utilizing the identification band to perform an entitlement transaction in steps 310 through 316, the wearer removes the identification band. The wearer may do so, for example, after leaving an entertainment venue. The sentinel circuit of the identification band detects removal of the identification band by utilizing, for example, a conductive clasp such as conductive clasp 108 in
Subsequently, step 310 of flowchart 300 is repeated, as shown in
In step 312 of flowchart 300, the first venue transceiver determines that the first profile is stored in the memory of the identification band, but is invalid. Because the identification band has previously been associated with a wearer, the wearer is prompted to provide a second profile (e.g., again present a biometric such as a fingerprint to a scanner) in step 320 of flowchart 300. The wearer thus provides a second profile that is compared to the invalidated first profile stored in the memory of the identification band. In step 322, if the second profile uniquely identifies (e.g., matches) the first profile, the identification band is successfully re-associated to the wearer, and flowchart 300 proceeds to and repeats steps 316 and 318.
If the second profile does not uniquely identify the first profile, the identification band is not successfully re-associated to the wearer. Thus, flowchart 300 proceeds from step 322 to 324, instead of returning to step 316. This may occur when, for example, the wearer attempting to re-associate with the identification band is not the same wearer who originally associated with the identification band. In step 324, the wearer cannot complete an entitlement transaction, and must return to step 310 and, for example, return the identification band to the correct wearer.
In the manner described above, the invention as shown in exemplary identification band 100, exemplary system 200, and exemplary flowchart 300 achieves secure association of an identification band to a wearer and overcomes the drawbacks of conventional solutions. Identification bands utilizing the invention may, for example, be associated, dissociated, and re-associated to wearers using novel sentinel circuits and other systems or methods as described above. The drawbacks of conventional solutions, which are, for example, less secure, are avoided.
