The session management module 410 is for managing interaction between the system user 210 of
The session management module 410 can include an authentication module 422 for authenticating the system user 210 when accessing the information vault 218. As an example, the user authentication module 422 can implement a multi-factor authentication, such as a token system, to validate and authenticate the system user 210 when accessing the vault user account 220.
The authentication module 422 can provide secure access to the information vault 218. For example, the authentication module 422 can implement a zero-knowledge system to provide end-to-end encryption of the user information 212. More specifically, the zero-knowledge system prevents the user information 212 from being stored on the user device 216.
The session management module 410 can transmit the user information 212 to the information vault with an information transfer module 424. In an implementation, the information transfer module 424 can generate transmission encrypted information 426 from the user information 212 received on the user device 216. The transmission encrypted information 426 is information that is encrypted for transmission between two devices. For example, the user information 212 received on the user device 216 can be encrypted with an encryption key received from the security module 414, which will be discussed in detail below. The information transfer module 424 can transmit the transmission encrypted information 426 to the information vault 218 for storage.
The computing system 100 can implement the information storage module 412 to process the user information 212 for secure storage in the information vault 218. For example, the information storage module 412 can process the user information 212 by encrypting the user information 212, including the electronic files 214 of
The information storage module 412 can encrypt the user information 212 for storage with a storage encryption module 430. For example, the storage encryption module 430 can utilize an information storage key 432, which is the encryption key for storing the user information 212. As a specific example, the storage encryption module 430 can implement an encryption scheme, including the information storage key 432, such as a military grade 256-Advanced Encryption Standards (AES), to generate vault encrypted information 434 from the the user information 212. The information storage key 432 can be provided by the security module 414, which will be discussed below.
The information storage module 412 can chunk the vault encrypted information 434, including the electronic files 214 that have been encrypted, with an information segmentation module 436. For example, the information segmentation module 436 can generate information chunks 438 from the vault encrypted information 434 with a data chunking scheme.
It has been discovered that segmenting the user information 212 into the information chunks 438 after encryption, such as after generating the vault encrypted information 434 from the user information 212, provides increased security for the user information 212. More specifically, the individual instances of the information chunks 438 cannot be de-encrypted to provide portions of the user information 212 since all the individual instances of the information chunks 438 are needed to fully de-encrypt the user information 212. Conversely, providing encryption following segmenting the user information 212 can lead to vulnerability of the user information 212 since de-encryption of an individual instance of the information chunks 438 can still provide a portion of the user information 212.
For added security, the information storage module 412 can store each of the information chunks 438 of the user information separately to ensure that the user information 212 is unreadable while in storage. More specifically, each of the information chunks 438 can be stored in non-sequential or adjacent physical or logical addresses within the storage medium, such as the second storage unit 346 of
The computing system 100 can include the security module 414 for implementing a security protocol 222 for the computing system 100. The security protocol 222 is a scheme to protect information. For example, the security protocol 222 can be a scheme to protect against or prevent unauthorized access to the user information 212 in the information vault 218 through hacking, cyber-attacks, or “phishing attacks.”
In one implementation, the security protocol 222 can include a scheme to provide encryption for the user information 212. For example, the security module 414 can include an encryption management module 450 to provide and manage encryption schemes for the computing system 100, including to provide and maintain the encryption keys and cyphers for the information vault 218.
More specifically, the encryption management module 450 can provide each of the accounts, such as the vault user account 220, with the vault account encryption key 452, which is unique to the vault user account 220 and ensures single access to the vault user account 220. For example, the encryption management module 450 can provide unique encryption keys for each instance of the vault user account 220 during transmission of the user information 212 with a transfer encryption scheme 454. As a specific example, transfer encryption scheme 454 can include a high-level Transport Layer Security (TSL)/Secure Socket Layers (SSL), such as a trusted 2048-bit certificate, and a Secure Hash Algorithms (SHA), such as a SHA-256, for secure connection between an internet browser used on the first device 102 and the information vault 218.
Further, the encryption management module 450 can implement various encryption schemes to encrypt the user information 212 for storage in the information vault 218. As a specific example, the encryption management module 450 can implement a rotating encryption key to generate the protected the user information 212, which can rotate the encryption key after specified period of time, such as a number of days. In another specific example, the encryption management module 450 can implement a double encryption scheme. In yet a further example, the encryption management module 450 can rotate an encryption cipher 456 for the information vault 218. More specifically, the computing system 100 can incorporate an object oriented programming architecture that enables the encryption management module 450 to rotate the encryption cipher 456.
In another implementation, the security protocol 222 can provide detection and measures to address a breach in security for the user information 212. More specifically, the security protocol 222 can include a breach protection protocol 474 to protect against solicitation based attacks, such as phishing attacks. In general, the breach protection protocol 474 can determine the occurrence of a security breach 472 through receipt of an electronic communication 476 from an electronic contact address created for the sole purpose of triggering an alert to the occurrence of the security breach. For example, the security module 414 can include a breach protection module 470 to implement the breach protection protocol 474 by generating a breach detection contact address 478, which can be used to determine the security breach 472.
The breach protection module 470 can generate the breach detection contact address 478 with a security contact generation module 480 for the vault user account 220. The breach detection contact address 478 is a contact address for the sole purpose of alerting the computing system 100 of the security breach 472 to the vault user account 220. As an example, the security contact generation module 480 can generate the breach detection contact address 478 upon creation of the vault user account 220. To continue the example, the breach protection module 470 can generate the breach detection contact address 478 dynamically as an electronic mail (e-mail) contact or address. The breach detection contact address 478 can be included in a contact list 484, such as an address book in a communication account or client, for a user electronic contact address 488, such an e-mail address, of the system user 210.
The breach protection module 470 can determine that the security breach 472 to the vault user account 220 has occurred based on receiving the electronic communication 476 from the user electronic contact address 488 to the breach detection contact address 478. In general, when the security breach 472 through a phishing attack occurs in the electronic contact account 486 of the system user 210, the attacking entity, such as malware, will user or steal the user electronic contact address 488 to conduct subsequent or additional attacks, such as sending out mass phishing e-mails, to the contacts in the contact list 484 of the system user 210 from an attack source 490, such as an internet protocol (IP) address. In this case, the breach detection contact address 478 will be included in the subsequent or additional attacks. Since the breach detection contact address 478 is unique for each instance of the vault user account 220, once the electronic communication 476 from the user electronic contact address 488 addressed is received at the breach detection contact address 478, the breach protection module 470 can match to the breach detection contact address 478 that was specifically generated for the vault user account 220 to determine that the security breach 472 has occurred.
When the security breach 472 is determined, the security module 414 can implement a security measure 494 with a security measure module 492. The security measure 494 is an action taken in response to the security breach 472. The security measure 494 can include a number of implementations individually or in combination. For example, in one implementation, the security measure 494 can include an account lock 496 for the vault user account 220. The account lock 496 prevents all access to the vault user account 220 that has experienced the security breach 472. The account lock 496 can be lifted once the system user 210 clears security verification to reestablish control of the account, such as answering security questions and change password to the vault user account 220.
In another implementation, the security measure 494 can include an address block 497. The address block 497 prevents attacks for unauthorized access to the vault user account 220 from the attack source 490.
