Abstract
The present disclosure relates to caching content at a device in a group of co-located devices whose owners share social network connections. In one embodiment, a method generally includes electing the device as a leader device based, at least in part, on shared social network connections associated with owners of each device in the group. The device receives a data request from a first user device and searches a cache for the data. If the data exists in the cache, the data is encrypted using an encryption key associated with an owner of the first user device transmitted to the first user device. Otherwise, the device requests the data from the content provider, receives an encrypted copy of the data, decrypts the data, and uses the encryption key associated with the owner of the first device to generate and transmit an encrypted message including the data to the first device.
