Method, apparatus and computer program product for processing an electronic request to access a computerized resource

An apparatus, comprising:

• memory;
• and
• processing circuitry coupled to the memory, the memory storing instructions which, when executed by the processing circuitry, cause the processing circuitry to:
• receive an electronic request to access a computerized resource, wherein the electronic request comprises a user identifier identifying a user associated with the electronic request, a first access token, and an index value;
• in response to receiving the electronic request, retrieve a token seed associated with the index value from a data source;
• generate a second access token based on the retrieved token seed and the user identifier identifying the user;
• compare the first and second access tokens to determine a similarity between the respective access tokens;
• based on the similarity between the respective access tokens, determine whether to allow the user access to the computerized resource;
• wherein the data source comprises a plurality of entries, each entry including an index value and a token seed for use in access token generation during discrete time periods, each entry being updated upon the expiration of the discrete time period related thereto such that the token seed is replaced with a different token seed but the index value remains the same;
• further wherein retrieving a token seed associated with the index value from the data source, comprises:
• identifying the entry associated with the index value;
• and
• returning the token seed in the identified entry for use in the generation of the second access token.

A computer program product having a non-transitory computer readable medium which stores a set of instructions, the set of instructions, when carried out by processing circuitry, causing the processing circuitry to perform a method of:

• receiving an electronic request to access a computerized resource, wherein the electronic request comprises a user identifier identifying a user associated with the electronic request, a first access token, and an index value;
• in response to receiving the electronic request, retrieving a token seed associated with the index value from a data source;
• generating a second access token based on the retrieved token seed and the user identifier identifying the user;
• comparing the first and second access tokens to determine a similarity between the respective access tokens;
• based on the similarity between the respective access tokens, determining whether to allow the user access to the computerized resource;
• wherein the data source comprises a plurality of entries, each entry including an index value and a token seed for use in access token generation during discrete time periods, each entry being updated upon the expiration of the discrete time period related thereto such that the token seed is replaced with a different token seed but the index value remains the same;
• further wherein retrieving a token seed associated with the index value from the data source, comprises:
• identifying the entry associated with the index value;
• and
• returning the token seed in the identified entry for use in the generation of the second access token.
