Systems and methods for finding nearby users with common interests

A mobile device comprising:

• a transmitter to transmit a first set of movie interests associated with a first user;
• and
• an interface to notify the first user if a second mobile device associated with a second user has an interest in common with the first set of movie interests, and the second mobile device is within a specified proximity to the first mobile device, wherein the interface is configured to initiate a request to communicate with the second mobile device without revealing an identity of the first user;
• wherein at least one of a sound and a haptic response of the notification depends on a number of movie interests in common between the first and second sets of movie interests;
• wherein the interface is configured to receive a user preference defining the specified proximity around the mobile device to find other devices with common movie interests;
• wherein the interface is configured to receive a user preference to provide notifications within a specified time range.

A system comprising:

• a transceiver to receive a first set of movie interests of a first user from a first mobile device and a second set of movie interests of a second user from a second mobile device;
• a database to store the received first and second sets;
• and
• a processor to determine whether the first mobile device associated with the first set of movie interests of the first user is within a specified proximity of the second mobile device associated with the second set of movie interests of the second user where the first and second sets share at least one movie interest, wherein the transceiver is configured to notify at least one of the first and second mobile devices that the first and second mobile devices are within the specified proximity, and the first and second sets share at least one movie interest, and wherein the transceiver is configured to provide notifications within a specified time range;
• wherein at least one of a sound and a haptic response of the notification depends on a number of movie interests in common between the first and second sets of movie interests;
• wherein the transceiver is configured to notify at least one of the first and second mobile devices that the first and second mobile devices are within the proximity and the first and second sets share at least one movie interest without revealing an identity of the first user or the second user.
