A system and method provide efficient, secure and highly reliable authentication for transaction processing and/or access control applications in which only biometric input is required from the user. A Personal Digital Key stores a biometric profile that comprises a representation of physical or behavioral characteristics that are uniquely associated with an individual that owns and carries the PDK. The PDK wirelessly transmits the biometric profile over a secure wireless transaction to a Reader for use in a biometric authentication process. The Reader compares the received biometric profile to a biometric input acquired at the point of transaction in order to determine if the transaction should be authorized.

Communications over short-range connections are used to facilitate whether access to resources is to be granted. For example, upon device discovery of one of an electronic user device and an electronic client device by the other device over a Bluetooth Low Energy connection, an access-enabling code associated with a user device or account can be evaluated for validity and applicability with respect to one or more particular resource specifications. User identity can be verified by comparing the user against previously obtained biometric information.

A physical security system and method for effecting a temporary access permission change are disclosed. The method includes analyzing context information, corresponding to a defined and applied, time-limited video redaction, to responsively define the temporary access permission change impacting a physical access control system of the physical security system. The method also includes effecting the temporary access permission change to at least make entry via an at least one entry barrier of the physical access control system more restricted than before the effecting of the temporary access permission change.

An authentication server includes a user registration unit, a service registration unit, and a storage unit. The user registration unit acquires a first ID that uniquely determines a user in a system and first biological information that is used for authentication of the user. The service registration unit processes a service registration request that is transmitted from a service provider of a service that the user wishes to use and that includes the first ID and a second ID that identifies the service provider. The service registration unit generates a third ID that is uniquely determined by a combination of the user and the service provider and transmits the third ID to the service provider. The storage unit stores the first biological information, the first ID, the second ID, and the third ID in association with each other.

A visitor management apparatus 1 is provided with: an identification information acquiring part 11 for acquiring visitor identification information of a visitor coming to a building, an evaluation value acquiring part 12 for acquiring evaluation value for the visitor by a resident living in the building, a storing part 13 for storing the visitor identification information corresponding to the visitor and the evaluation value corresponding to the visitor in association with each other, and a providing part 14 for providing the visitor identification information and the evaluation value associated with each other and stored in the storing part 13 to an other building differing from the building.

A system and method provide efficient, secure, and highly reliable authentication for transaction processing and/or access control applications. A personal digital key (PDK) is programmed using a trusted programming device to initialize and/or register the PDK for use. In one embodiment, the initialization and registration processes are administered by a specialized trusted Notary to ensure the processes follow defined security procedures. In a biometric initialization, the programming device acquires a biometric input from a user and writes the biometric data to a tamperproof memory in the PDK. In registration, the Programmer communicates to one or more remote registries to create or update entries associated with the user PDK. Once initialized and registered, the PDK can be used for various levels of secure authentication processes.

A facial recognition locker bank is provided. In an example, the facial recognition locker bank captures an image of a user renting a locker at the locker bank. A vector may be computed based on the image, and the vector is used for facial recognition. The vector may be shared with other associated locker banks over a local area network so that the other locker banks can identify the user. For example, the other locker banks may identify the user and direct the user to the locker bank at which the user rented the locker. When the user returns to the locker bank, a second image of the user is captured, and a second vector is computed. Based on a comparison between the vectors, the user can be identified, and the rented locker can be unlocked.

A computer alters at least one recognizable metric or text in a digitally encoded photographic image by operating an alteration algorithm in response to user input data while preserving an overall aesthetic quality of the image and obscuring an identity of at least one individual or geographic location appearing in the image. An altered digitally-encoded photographic image prepared by the altering of the at least one recognizable metric or text in the image is stored in a computer memory. User feedback and/or automatic analysis may be performed to define parameter values of the alteration algorithm such that the alteration process achieves preservation of aesthetic qualities while obscuring an identity of interest.
