Abstract: Re-Identification of physical objects in an image background is made possible by the use of temporary data objects (i.e., video cookies). Image data including an image object representing a physical object in at least one of a plurality of backgrounds is pre-stored in a database. Identification data for the image object and image background data is extracted from the image object and a comparison is made to determine if the identification data matches identification data in the database. In the event no match is found, a temporary data object is created and stored in the database that links the identification data and the image background data. If an identification data match is found, it is determined whether a temporary data object exists in the database. If no temporary data object exists, one is created and stored in the database. If a temporary data object is determined to exist in the database, it is determined whether the temporary data object fulfills a predetermined condition(s).

Abstract: An electronic device generates a dynamic security code for a card transaction, e.g. a card not present transaction. The electronic device receives a user request to generate a dynamic security code.

The electronic device causes the dynamic security code to be displayed on a display of the electronic device. The electronic device may be capable of computing a dynamic security code for a plurality of different cards. The electronic device may be a smart phone, a tablet, or a personal computer.

Abstract: To allow access to encrypted data stored in the memory of a user terminal, the corresponding secret encryption key is stored in a secure element integrated into the user terminal and this secure element serves as a highly secure relay toward an access device to this data, used by a third party. To do so, a secure communication channel is established between the third party and the secure element. The EAC standard allows mutual authentication accompanied by the establishment of such a secure communication channel. The secure element performs an encryption conversion of the data so that the latter is protected by a session (or transport) key associated with the secure communication channel, and no longer by the initial secret key. The third party can thus access the encrypted data without even knowing the initial secret key.

Abstract: In general, one innovative aspect of the subject matter described in this specification may be embodied in methods that may include validating user data pages extracted from a digital identification in circumstances where a user device that includes the digital identification is either unavailable or presently lacks network connectivity. For instance, an authorized device may be used to extract user data pages from the digital identification by either exchanging communications with the user device using a proximity-based data exchange protocol, or by using a physical identification card to identify the digital identification on a user record. The user data pages may then be validated by comparing checksums associated with user data pages against the checksums within the user record, and decrypting the user data pages using a decryption key that is variably designated by a security status assigned to the digital identification.
