Contact matching method, instant messaging client, server and system

摘要

A computer-implemented method of providing matching information to prospective first and second users is performed at a server, the method including: receiving first audio data and first user information; receiving second audio data, and second user information; storing a first timestamp of the first audio data and first user information and a second timestamp of the second audio data and second user information; performing analysis processing on the first audio data to obtain first feature information, and performing analysis processing on the second audio data to obtain second feature information; judging whether the first timestamp and the second timestamp and the first feature information and the second feature information match; and if the first and second times of receipt and the first and second feature information match, sending the first user information to the second user and sending, by the server, the second user information to the first user.

1. A method of exchanging contact information between a first user and a second user, the method comprising:
at a server having one or more processors and memory storing programs to be executed by the processors:
receiving first audio data from a first mobile device used by the first user and generating a first timestamp indicative of receipt of the first audio data at the server;receiving second audio data from a second mobile device used by the second user and generating a second timestamp indicative of receipt of the second audio data at the server, wherein the second mobile device is distinct from the first mobile device;processing the first audio data to obtain first audio frequency characteristics, further including sequentially sampling audio frequencies of the first audio data to obtain a first set of sampled audio frequencies;processing the second audio data to obtain second audio frequency characteristics, further including sequentially sampling audio frequencies of the second audio data to obtain a second set of sampled audio frequencies;determining, based on the first audio data received from the first mobile device and the second audio data received from the second mobile device, whether a location of the first user matches a location of the second user, including:
determining whether the first audio frequency characteristics match the second audio frequency characteristics to within a predefined threshold, further including determining whether the first set of sampled audio frequencies and the second set of sampled audio frequencies have at least a predefined number of consecutive similar sampling frequencies, wherein a sampled audio frequency in the first set of sampled audio frequencies is similar to a corresponding sampled audio frequency in the second set of sampled audio frequencies if a difference between the two sampled frequencies is less than a predefined threshold level;determining whether the first timestamp matches the second timestamp to within a predefined difference; andin accordance with a determination that the first user's location matches the second user's location:
sending, to the second mobile device, first contact information corresponding to the first user.
