Methods, portable electronic devices, systems and computer program products for automatically creating social networking services (SNS)

A system for automatically creating a social networking service session, comprising:

• first and second devices, the first device being configured to generate a first audio and/or video fingerprint of an audio and/or video event at the first device and transmit the first audio and/or video fingerprint, the first audio and/or video fingerprint having a first predetermined length (T);
• and
• a server configured to:
• receive periodic transmissions of a second audio and/or video fingerprint from the first device, the second t audio and/or video fingerprint having a second predetermined length (t), smaller than the first predetermined length(T), and including data associated with the audio and/or video event that is later in time than data included in the first audio and/or video fingerprint;
• compare a third audio and/or video fingerprint having the first predetermined length (T) from the second device to the first or second audio and/or video fingerprint generated at the first device;
• automatically create the SNS session if it is determined that the third audio and/or video fingerprint having the first predetermined length (T) from the second device includes a portion of the first audio and/or video fingerprint or the second audio and/or video fingerprint periodically transmitted from the first device;
• and
• join the first and second devices to the SNS session.

A computer program product for automatically creating a social networking service (SNS) session, the computer program product comprising:

• a non-transitory computer-readable storage medium having computer-readable program code embodied in said medium, said computer-readable program code comprising:
• computer readable program code configured to generate at and transmit from a first device a first audio and/or video fingerprint of an audio and/or video event, the first audio and/or video fingerprint having a first predetermined length (T);
• computer readable program code configured to periodically transmit, from the first device, a second audio and/or video fingerprint to a server, the second audio and/or video fingerprint having a second predetermined length (t), smaller than the first predetermined length (T), and including data associated with the audio and/or video event that is later in time than data included in the first audio and/or video fingerprint;
• and
• computer readable program code configured to join the SNS session automatically created by the server responsive to receipt, at the server, of a third audio and/or video fingerprint having the first predetermined length (T) from a second device that includes a portion of the first audio and/or video fingerprint or the second audio and/or video fingerprint periodically transmitted from the first device.
