Abstract
A one-time password may be used and generated using transformation rules. A one-time password transformation rule is received. The one-time password is sent to a user. A response to the one-time password is received. The user is selectively authenticated based on the response corresponding to the one-time password as transformed by the one-time password transformation rule. The one-time password transformation rule may include one or more operations, such as mathematical operations that may be static operations or dynamic operations that change as a function of time. Related systems, devices, methods and computer program products are described.
Claims20
A method comprising:
- sending a one-time password to a user;
- receiving a response to the one-time password;
- and
- selectively authenticating the user based on the response corresponding to the one-time password as transformed by the one-time password transformation rule.
A computer system comprising:
- a processor;
- and
- a memory coupled to the processor and comprising computer readable code that, when executed by the processor, causes the processor to perform operations comprising:
- sending a one-time password to a user;
- receiving a response to the one-time password;
- and
- selectively authenticating the user based on the response corresponding to the one-time password as transformed by the one-time password transformation rule.
A computer program product comprising:
- a computer readable storage medium having computer readable program code embodied in the medium that, when executed by a processor of a computer system, causes the computer system to perform operations comprising:
- sending a one-time password to a user;
- receiving a response to the one-time password;
- and
- selectively authenticating the user based on the response corresponding to the one-time password as transformed by the one-time password transformation rule.
