Assignee: DE-IDENTIFICATION LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 10:
11. A data authentication system comprising:
a computerized device, comprising data items for authentication;
a database, comprising de-identified data, and
a processor, coupled to the computerized device and to the database, wherein the processor is configured to:
receive a data item from a user;
create a de-identified data item by applying a de-identification function r on the data item,
training, by the processor, a transformation function p and a key generation function with a loss function of d1(f(r(xi), (p(xj, kxi)), f(xi, xj)), where (xi, xj) are a pair of training data items, d1, is a machine learning function, and f is a recognition function;
generating, by the processor, using the key generation function, an authentication key, based on the received data item and the de-identified data item;
receive a new data item for authentication;
generate a new de-identified data item by applying the transformation function on the new data item and the authentication key; and
compare the new de-identified data item with the de-identified data item to authenticate the identity of the user.
