Abstract: A system and corresponding method for protecting the privacy associated with one or more encrypted data records includes a host device and a security device. The host device is operable to allow access to the one or more data records being in an encrypted format including encrypted data records, and upon an attempt to access the one or more encrypted data records transmitting a request for an encryption key for unencrypting the encrypted data records to a security device. The security device is remote from the host device and is operable to require one or more actions being taken by a user as a condition to providing the encryption key, and upon the success of the actions as the condition, transmitting the encryption key to the host device. The host can then unlock the encrypted data records upon receipt of the encryption key.

Abstract: A system and method are provided for validating executable program code operating on at least one computing device. Program instructions that include a request for access to sensitive information are executed on a first computing device. An authentication request for access to the electronic information is sent from the first computing device to a second computing device. In response to the authorization request, a challenge is sent from the second computing device to the first computing device. The first computing device executes the challenge and generates an authentication response that includes at least one memory object associated with the program instructions.

Abstract: A method for protecting the transfer and storage of data by encryption using a private key encrypted with a first key encrypting key, which is encrypted using a second key encrypting key. This latter key is encrypted using a hashed passphrase value, obtained by hashing a passphrase known only to the authorized user. Upon receipt of a request initiated by the user by entering a passphrase, a first hashed passphrase is transferred to a first data processing system, where it is compared with a predefined hash string. If they match, the first data processing system transfers to a second data processing system the encrypted second key encrypting key. A candidate key is obtained by decrypting the encrypted second key encrypting key using a second hashed passphrase. Upon successful validation of the candidate key, the passphrase is verified and the user is authenticated.

Abstract: The present invention relates to a method and apparatus for distributing, issuing, validating and implementing pre-paid cards to be used in e-commerce and telephone calling applications. In particular, the present invention includes a Prepaid Validation Device (hereinafter, “PVD”) for issuing prepaid cards, the PVD having a removable Memory Unit on which Personal Identification Numbers (“PINS”) are stored. The PINS are divided into PIN groups and uploaded to Memory Units by a Reseller of PINS. A database of PINS is stored in the Memory Unit, where the database is divided into several layers of PINS. Initially, the first layer of PINS is activated and the remaining layers are inactive and inaccessible. However, the remaining layers may be activated by placing an activation order and then accessed by an PIN unlocking procedure.
