Abstract: The present disclosure provides a method for exchanging contact information, comprising detecting a first exchange event on a first mobile electronic device of a first user and initiating the exchange of contact information between the first mobile electronic device and a second mobile electronic device of another user that has detected a second exchange event. Next, contact information of the first user is transmitted from the first mobile electronic device to the second mobile electronic device and contact information of the second user is received at the first mobile electronic device.

Abstract: A method for contact management comprises retrieving, using a mobile electronic device of a user, contact information from multiple external sources. The method next comprises storing said contact information in a memory location of said mobile electronic device. Next, the method comprises determining with a computer processor whether contact information from a portion of said multiple sources at least partially overlaps with contact information from a remainder of said multiple sources. The method next comprises either merging the contact information to generate a consolidated contact record or splitting the contact information to generate split contact records based on the determining the overlap. And then the method comprises storing said consolidated contact record or split contact records in a memory location of said mobile electronic device.

Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer readable media, for generating a message associated with a user, wherein the user is associated with a plurality of peers in a social network. A subset of peers is randomly chosen from the plurality of peers. The message is sent to the subset of peers. Data pertaining to one or more behaviors from one or more peers of the plurality of peers is collected. A time for a target behavior is evaluated as a function of who received the message and who did not receive the message. From the evaluation, particular members of the social network are identified.
