A biometric enrollment system can include a processor and a data store that stores one or more TPS templates and a sample population. The processor can be configured to receive a reference template associated with a subject, generate a cohort set based on a plurality of templates from the sample population, and perform a one-to-many comparison process on the reference template and the cohort set, wherein an output of the one-to-many comparison process comprises one or more cohort vectors. The processor can normalize the one or more cohort vectors to obtain one or more normalized cohort vectors, and can apply a lossy transformation to the one or more normalized cohort vectors. An output of applying the lossy transformation can comprise one or more transformed, privacy-secured (TPS) templates that are stored in the database.

The disclosed exemplary embodiments include computer-implemented devices, apparatuses, and processes that, among other things, perform dynamic biometric authentication based on distributed ledger data. For example, a device may compute a first hash value based on first biometric data captured by a sensor unit, and may transmit a request to, and receive a response from, a computing system across a communications network via the communications unit. The request may cause the computing system to execute instructions maintained within the distributed ledger data, and to extract second biometric data maintained within an element of the distributed ledger data. The second biometric data may include a second hash, which the computing system may incorporate into the response. The device may authenticate an identity associated with the device when the first hash value corresponds to the second hash value incorporated within the response.

Data is received as part of an authentication procedure to identify a user. Such data characterizes a user-generated biometric sequence that is generated by the user interacting with at least one input device according to a desired biometric sequence. Thereafter, using the received data and at least one machine learning model trained using empirically derived historical data generated by a plurality of user-generated biometric sequences (e.g., historical user-generated biometric sequences according to the desired biometric sequence, etc.), the user is authenticated if an output of the at least one machine learning model is above a threshold. Data can be provided that characterizes the authenticating. Related apparatus, systems, techniques and articles are also described.

The present invention discloses methods and systems for performing at least one action at a system according to a user's gesture information. The required steps comprises of capturing the user's gestures information by a mobile apparatus, wherein the apparatus comprises an antenna, a processor, a storage medium, at least one accelerometer, wherein the accelerometer has at least 3 axis; comparing gesture information against one or more predefined gesture information at the mobile apparatus and when the gesture information matches a predefined gesture information, the mobile apparatus selects a first identity based on the predefined gesture information, sends encrypted information to a system through a reader wherein the encrypted information comprises the predefined gesture information, the first identity, a timestamp, and a device identity. The system performs at least one action according to the encrypted information. When the gesture information does not match any pre-defined gesture information, the mobile apparatus sends a failure notice to the user. The mobile apparatus or device does not send the encrypted information unless the device is physically close to the reader by a first wireless signal strength.

An access manager determines whether access will be granted to a guarded species or space utilizing a controller including a digital processor with a memory for storing an ID library and a transducer block coupled with the processor for accessing a plurality of different ID types and an actuator block coupled with the processor for unblocking a normally locked portal to the guarded space.

Techniques for DNS registry facilitated assignment of a DNS domain name registered to a registrant as a blockchain user address in a blockchain network are presented. The techniques can include providing, by a DNS registry, a public key and a computer executable registry signature verification program configured to use the public key to validate signatures made using the private key for addition to a block in a blockchain of the blockchain network. The techniques can also include receiving a request for a proof of registrar of record, and providing a proof of registration message, such that the registry signature verification program validates the signature using the public key, and the blockchain network receives and stores in the blockchain an association between the domain name and an existing blockchain user address for the registrant.

A method for facilitating secure communication between a user device and a network device. Encrypted data from a user device is received at the network device. The encrypted data is encrypted based on first physiological data captured by a first sensor of the user device. The first physiological data is representative of a physiological characteristic of a user of the user device. A second sensor of the network device captures second physiological data representative of the physiological characteristic of the user. A common key for encrypting further data transferred between the user device and the network device is determined, based on the encrypted data and the second physiological data. Further aspects relate to other methods for facilitating secure communication between a user and network device, a network, and a method of operating a network.
