US 11,310,046 B2 · Systems and methods for secure identification retrieval

Abstract

The present disclosure provides systems and methods for secure identification retrieval. The method includes retrieving a value of a periodic variable and calculating a plurality of query tokens from a corresponding plurality of client device identifiers and the value of the periodic variable. Each query token is associated with a corresponding client device identifier in a first database. The method further includes receiving a first query token calculated from a client device identifier of the first client device and the value of the periodic variable and identifying a second query token of the calculated plurality of query tokens in the first database matching the first query token. The method further includes, responsive to the identification, retrieving the associated client device identifier and retrieving one or more characteristics of the first client device according to the associated client device identifier. The method further includes transmitting the retrieved one or more characteristics.

Dependent claims

A method for secure identification retrieval, comprising:

retrieving, by a server device, a value of a periodic variable;
calculating, by the server device, a plurality of query tokens from a corresponding plurality of client device identifiers and the value of the periodic variable, each query token associated with a corresponding client device identifier in a first database;
receiving, by the server device from a first client device, a first query token calculated from a client device identifier of the first client device and the value of the periodic variable;
identifying, by the server device, a second query token of the calculated plurality of query tokens in the first database matching the first query token;
responsive to the identification, retrieving, by the server device, the associated client device identifier;
retrieving, by the server device from a second database, one or more characteristics of the first client device according to the associated client device identifier;
and
transmitting, by the server device to the client device, the retrieved one or more characteristics.

5 more elements

A server device for secure identification retrieval, comprising:

a network interface in communication with a first client device of a plurality of client devices;
a memory device storing a first database comprising a plurality of query tokens and a corresponding plurality of associated client device identifiers, and a second database comprising the plurality of client device identifiers and associated device characteristics;
and
a processor, configured to:
retrieve a value of a periodic variable,
calculate the plurality of query tokens from the corresponding plurality of client device identifiers and the value of the periodic variable,
receive, via the network interface from the first client device, a first query token calculated from a client device identifier of the first client device and the value of the periodic variable,
identify a second query token of the calculated plurality of query tokens in the first database matching the first query token,
responsive to the identification, retrieve, from the first database, the associated client device identifier,
retrieve, from the second database, one or more characteristics of the first client device according to the associated client device identifier, and
transmit, via the network interface to the client device, the retrieved one or more characteristics.
