Abstract
Various embodiments of the teachings herein include a device searching method. An example method may include: acquiring fingerprint information of a first device in a first network; acquiring fingerprint information of each device in a second network; for each device in the second network, calculating a similarity between the fingerprint information of said device and the fingerprint information of the first device; and according to all the calculated similarities, judging whether the first device should be a device in the second network.
Claims11
A device searching method comprising:
- acquiring fingerprint information of a first device in a first network;
- acquiring fingerprint information of each device in a second network;
- for each device in the second network, calculating a similarity between the fingerprint information of said device and the fingerprint information of the first device;
- and
- according to all the calculated similarities, judging whether the first device should be a device in the second network.
2 more elements
A device searching apparatus comprising:
- an information acquisition module to:
- acquire fingerprint information of a first device in a first network, and
- acquire fingerprint information of each device in a second network;
- and
- a processing module to, for each device in the second network, calculate a similarity between fingerprint information of said device and fingerprint information of the first device and, according to all the calculated similarities, judge whether the first device should be a device in the second network.
2 more elements
The apparatus as claimed in claim 15, wherein:
- the fingerprint information comprises:
- at least one piece of first type fingerprint information comprised in the first device and each device in the second network, and
- at least one piece of second type fingerprint information comprised in only some devices among all devices including the first device and each device in the second network;
- when the processing module calculates the similarity between the fingerprint information of said device and the fingerprint information of the first device,
- for each piece of the first type fingerprint information, the closer a value of the first type fingerprint information of said device to a value of the first type fingerprint information of the first device, the higher the similarity between the fingerprint information of said device and the fingerprint information of the first device and,
- for the at least one piece of second type fingerprint information, the closer the structure of the at least one piece of second type fingerprint information contained in said device to the structure of the at least one piece of second type fingerprint information contained in the first device, and the closer the values of the same item of the second type fingerprint information, the higher the similarity between the fingerprint information of said device and the fingerprint information of the first device.
