Abstract

A service receives a request from a user of a group of users to perform one or more operations requiring group authentication in order for the operations to be performed. In response, the service provides a first user of the group with a musical seed and an ordering of the group of users. Each user of the group applies a transformation algorithm to the seed to create an authentication claim. The service receives this claim and determines, based at least in part on the ordering of the group of users, an ordered set of transformations, which are used to create a reference audio signal. If the received claim matches the reference audio signal, the service enables performance of the requested one or more operations.

Claims20

Dependent claims

A computer-implemented method comprising:

under the control of one or more computer systems configured with executable instructions,
receiving a request to perform one or more operations;
providing a musical seed and an ordering of a group of users, the group of users comprising a first user assigned with a first audial transformation and a second user assigned with a second audial transformation, the first audial transformation being different from the second audial transformation;
receiving an authentication claim comprising an encoding of an audio signal;
determining, based at least in part on the ordering of the group of users, an ordered set of audial transformations;
applying the first audial transformation and the second audial transformation to the musical seed according to the determined ordered set of audial transformations to generate an encoding of a reference audio signal;
determining that the reference audio signal matches the audio signal of the authentication claim;
and
performing the one or more operations.

6 more elements

A non-transitory computer-readable storage medium having stored thereon executable instructions that, as a result of being executed by one or more processors of a computer system, cause the computer system to at least:

receive an authentication claim for a group of entities comprising a first entity assigned with a first audial transformation and a second user assigned with a second audial transformation, the first audial transformation being different from the second audial transformation;
determine, based at least in part on the group of entities, the first audial transformation, and the second audial transformation, a set of audial transformations;
validate the authentication claim based at least in part on the determined set of audial transformations, an encoding of media, and the received authentication claim;
and
determine that one or more operations requiring authentication are authorized.
