Abstract
Methods, portable electronic devices, systems and computer program products are provided for automatically creating a social networking service (SNS) session. The methods include generating at and transmitting 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 has a first predetermined length (T). A second audio and/or video fingerprint is periodically transmitted to a server from the first device. The second audio and/or video fingerprint has a second predetermined length (t), smaller than the first predetermined length (T), and includes 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. The first device is joined to an SNS session, automatically created by the server, responsive to receipts 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.
