Description

Method for verifying playback information, electronic device and system performing the same The present disclosure relates to a method for verifying playback information, an electronic device and a system for performing the same. With the widespread distribution of digital audio and multimedia content, technologies for managing audio playback history on user terminals and servers are being developed. Conventionally, playback history was managed through integration between audio streaming servers and user accounts; however, with the development of various playback devices, there were limitations in managing the playback history of audio played on each device. Some systems have applied methods that synchronize all playback records to a server based on user account information or authenticate the time of music playback through Digital Rights Management (DRM) technology. However, this required a constant network connection, and if user account information or DRM keys were leaked, there was a possibility that illegal copying or false playback history could be registered. Furthermore, in environments where audio sources are stored and played on physical storage devices, it was difficult to obtain playback statistics by managing the playback history of audio sources played on the devices because genuine authentication of the storage devices themselves or mutual verification between playback devices was not sufficiently performed.
