Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather construed as limited to the embodiments set forth herein.
A first embodiment of the present invention provides a method for identifying a device, which is described below with reference to fig. 1.
As shown in fig. 1, in step S101, first file identification information of a first device sent by a client is received.
The client refers to a newly installed client on the first device.
The first device is a device provided with a client. The first device may be an electronic device such as a mobile phone and a tablet computer.
The first file identification information may be characteristic information of a file stored on the first device; the first file identification information may also be encoded information of characteristic information of a file stored on the first device. The characteristic information of the file may be name information of the file, content information of the file, or other attribute information of the file. For example, the first file identification information may be an MD5 code derived from an image in an album on the first device.
As shown in fig. 1, in step S102, second file identification information of the second device stored in advance is obtained.
The second device is a device already recorded by the server, the server allocates identification information for the second device, stores second file identification information of the second device, and the server can also record historical operation behavior information of a user of the second device and other information of the second device.
The second file identification information may be encoding information of characteristic information of a file stored on the second device. The second file identification information is generated in the same manner as the first file identification information. For example, if the first file identification information is obtained as follows: the method comprises the steps that a client side of first equipment firstly obtains photos stored on the first equipment in the last two years, then the photos are aggregated according to day units, an image set is generated by every day of photos, each image set generates an MD5 value, 365 x 2 MD5 values are generated in total, and the 365 x 2 MD5 values serve as first file identification information; the second file identification information is obtained as follows: the client of the second device firstly obtains the photos stored on the second device in the last two years, then aggregates the photos according to day units, generates an image set from the photos in each day, generates an MD5 value from each image set, generates 365 x 2 MD5 values in total, and takes 365 x 2 MD5 values as second file identification information.
As shown in fig. 1, in step S103, it is determined whether there is a second device matching the first device according to the first file identification information and the second file identification information.
The judging whether a second device matched with the first device exists according to the first file identification information and the second file identification information comprises the following steps:
judging whether second file identification information matched with the first file identification information exists or not;
if yes, determining that second equipment matched with the first equipment exists; the second equipment is equipment corresponding to second file identification information matched with the first file identification information;
and if not, determining that no second equipment matched with the first equipment exists.
The determining whether there is second file identification information that matches the first file identification information includes:
judging whether second file identification information with the similarity larger than a preset similarity threshold exists or not;
if so, determining that second file identification information matched with the first file identification information exists;
and if not, determining that second file identification information matched with the first file identification information does not exist.
Since the file information on the first device of the user may change, even if the first device and the second device are the same device, there may be some differences between the first file identification information and the second file identification information, so a reasonable similarity threshold may be set, and as long as the similarity between the first file identification information and the second file identification information is greater than the similarity threshold, it is determined that the first device and the second device are matched, that is, the first device and the second device are the same device.
For example, if the similarity threshold is set to 90%, and if the first file identification information 365 × 2 MD5 values and the second file identification information is also 365 × 2 MD5 values, when the MD5 value of the first file identification information and the MD5 value of the second file identification information are similar to each other by 90% or more, it is determined that the first device and the second device are matched; and when the value of the MD5 of the first file identification information is less than 90% of the value of the MD5 of the second file identification information, judging that the first device is not matched with the second device.
In order to more accurately match the first device and the second device, in addition to comparing the first file identification information and the second file identification information, a comparison of the first system identification information and the second system identification information may be performed, and when both the file identification information and the system identification information match, the first device and the second device are determined to match.
As an implementation manner, the server may further receive first system identification information of the first device, which is sent by the client; the first system identification information refers to system information for identifying the first device.
The first system identification information includes: the model of the first device, the version of the operating system, the bluetooth version, etc.
The judging whether a second device matched with the first device exists according to the first file identification information and the second file identification information comprises the following steps:
the determining whether a second device matched with the first device exists according to the first file identification information and the second file identification information, and the first system identification information and pre-stored second system identification information includes:
judging whether second file identification information with the similarity larger than a preset similarity threshold exists or not;
if so, determining that second file identification information matched with the first file identification information exists;
judging whether the first system identification information is consistent with second system identification information corresponding to second file identification information matched with the first file identification information;
when the first system identification information is judged to be consistent with the second system identification information, determining that a second device matched with the first device exists;
and when the first system identification information is judged to be inconsistent with the second system identification information, determining that no second equipment matched with the first equipment exists.
According to the method, the similarity between the second file identification information and the first file identification information is judged firstly, when the similarity is larger than the similarity threshold value, whether the first system identification information is consistent with the second system identification information is judged, and when the similarity is consistent with the second system identification information, the first equipment is matched with the second equipment, so that the correctness of the matching result of the first equipment and the second equipment is ensured, and the uniqueness of equipment identification is ensured.
As shown in fig. 1, in step S104, when the result of step S103 is yes, the identification information of the second device is sent to the client.
The identification information of the second device is stored in the server, and may refer to a record number of the second device in a database storing information of the second device.
As an implementation, the first embodiment of the present invention further includes: and updating the second file identification information to the first file identification information when the first device is matched with the second device.

As shown in fig. 2, in step S202, first file identification information of the first device is obtained according to the feature information of the file stored in the first device.
The first file identification information may be characteristic information of a file stored on the first device; the first file identification information may also be encoded information of characteristic information of a file stored on the first device. For example, the first file identification information may be an MD5 code derived from an image in an album on the first device.

The encoding the image in the preset time period to generate the first file identification information includes:
and generating an MD5 code according to the image in the preset time period, wherein the MD5 code is used as the first file identification information.
The generating of the MD5 code according to the image in the preset time period, taking the MD5 code as the first file identification information, comprises:
determining the unit time for aggregating the images in the preset time period and the number of the unit time contained in the preset time period;
aggregating the images in the preset time period by taking unit time as a unit to generate an image set of the number of the unit time contained in the preset time period;
generating an MD5 code for each image set;
and merging the MD5 codes of the number of the unit time included in the preset time period to generate the first file identification information.
