摘要： Systems and methods are disclosed for training a generative adversarial network (GAN) to transform images of one type (e.g., a selfie) to images of a second type (e.g.,. an ID document image). Once trained, the GAN may be utilized to generate an augmented training set that includes pairs of images (e.g., an image of the first type paired with an image of the second type, an image of the second type generated from an image of the first type paired with an image of the second type). The augmented training data set may be utilized to train a matching model to identify when subsequent input images (e.g., a selfie and an ID image, an ID image generated from a selfie and an actual ID image) match.

摘要： A method for performing a key recovery process is disclosed. The method comprises entering, in a user device, a user identifier unique to a user. The user device may then obscure the user identifier to form an obscured user identifier. The user device may then transmit the obscured user identifier to a first and second entity computer. The method may then include the first entity computer generating a first output using the obscured user identifier and a first share, and the second entity computer generates a second output using the obscured user identifier and a second share. As a response to transmitting the obscured identifier, the user device may receive the first output from the first entity computer and the second output from the second entity computer. The user device may then generate a secret key after processing the first output and the second output, completing the key recovery process.

摘要： A method is disclosed. The method includes a server computer receiving, from a user device, a first encrypted biometric template, wherein the server computer stores a plurality of encrypted enrollment biometric templates, and a table comprising a plurality of encrypted match values and corresponding unencrypted match values. The server computer can then, for each of the plurality of encrypted enrollment biometric templates, input the first encrypted biometric template and an encrypted enrollment biometric template into a function to obtain an encrypted match value. The server computer can then, for each of the plurality of encrypted enrollment biometric templates, determine if the encrypted match value corresponds to an unencrypted match value using the table, wherein the unencrypted match value is greater than a threshold. The server computer can then provide a notification to the user device or another device associated with the unencrypted match value.

摘要： Methods and systems for performing demographics filtering based on biometric information are disclosed. An access terminal can capture a biometric instance corresponding to a user, such as a fingerprint scan, iris scan, etc. The access terminal can determine demographics information from the biometric instance, such as the age, biological sex, or ethnicity of the user. The access terminal can compare the demographics information to demographics information stored on a group of mobile devices corresponding to a group of users, in order to identify candidate user mobile devices. Once candidate user mobile devices are identified, the access terminal can perform a biometric match between the biometric instance corresponding to the user and biometric instances stored on the candidate user mobile devices. Once a biometric match and the corresponding mobile device are determined, the access terminal can conduct a further interaction with the mobile device.

摘要： A method is disclosed. The method comprises receiving, by an identity network computer, a query set including a plurality of test identity attributes. After receiving the query set, the identity network computer may retrieve derivatives of identity attributes associated with a user, and an encrypted trapdoor, then compute an obscured query set using the query set, and optionally the derivatives of identity attributes. The identity network computer may transmit the obscured query set (i) and the encrypted trapdoor to a user device associated with the user, which generates and transmits a first modified trapdoor and the obscured query set to a relying party computer, or (ii) and a second modified trapdoor to the relying party computer. The relying party computer may thereafter use the obscured query set, and the first modified trapdoor or the second modified trapdoor, to determine if the identity attributes is a member of the query set.

摘要： A method is disclosed. An authentication node may receive a plurality of encrypted match values, wherein the plurality of encrypted match values were formed by a plurality of worker nodes that compare a plurality of encrypted second biometric template parts derived from a second biometric template to a plurality of encrypted first biometric template parts derived from a first biometric template. The authentication node may decrypt the plurality of encrypted match values resulting in a plurality of decrypted match values. The authentication node may then determine if a first biometric template matches the second biometric template using the plurality of decrypted match values. An enrollment node may be capable of enrolling a biometric template and storing encrypted biometric template parts at worker nodes.
