Embodiment 1

[0046] figure 1 This is a flowchart of the device identification method provided in Embodiment 1 of the present application. This embodiment provides a device identification method for determining whether a device used by a user to access an application or website through an account ID matches an identified device saved by the application or website, wherein the identified device saved according to the application or website The association information between the attribute of the sample device and the set of account IDs including the account ID is set with the weight of the value of the attribute of the sample device associated with the account ID.

[0047] The associated information includes at least one of the following: the number of times the account ID accesses the application or website through the value of the sample device attribute, the number of times the account ID accesses the application or website through the value of the sample device attribute, the number of t...

Embodiment 2

[0101] like image 3 As shown, this embodiment provides a weight calculation method for device identification, the method includes the following steps:

[0102] Step 301: Determine the association information between the sample device attribute of the identified device and the account ID set saved by an application or website;

[0103] Step 302: According to the association information, calculate the weight of one or more account IDs in the account ID set associated with the value of the sample device attribute;

[0104] Wherein, the weight of the account ID associated with the value of the sample device attribute is used to calculate the similarity between the device used by the user to access the application or website through the account ID and the identified device saved by the application or website, so as to According to the similarity, it is determined whether the device used by the account ID to access the application or website matches the identified device stored in...

Embodiment 3

[0186] Embodiments of the present application further provide a data processing electronic device for determining whether the device used by a user to access an application or website through an account ID matches an identified device saved by the application or website, wherein according to the data stored in the application or website Association information between a sample device attribute of an identified device and an account ID set including the account ID, provided with the account ID associated with the weight of the value of the sample device attribute, and the data processing electronic device includes a memory and a processing The memory is used to store a program for device identification, and the program for device identification is used to determine whether the device used by the user to access an application or website through an account ID matches the identified device saved by the application or website , when the program for device identification is read and ...

Abstract

The present invention discloses a device identification method for determining whether a device used by a user for accessing an application or a website through an account ID matches an identified device saved by the application or the website, wherein, according to association information between sample device attributes of the identified device saved by the application or the website and a set of account IDs including the account ID, the weight of the values of the sample device attributes associated with the account ID is set. The device identification method comprises: determining a matching value between a value of a to-be-identified device attribute of the device used by the account ID and a value of the sample device attribute of the identified device; and calculating similarity between the device used by the account ID and the identified device according to the matching value and the weight of the value of the sample ID associated with the account ID; and according to the similarity, determining whether the device used by the account ID matches the identified device. The present invention further discloses a weight calculation method for device identification.

Description

technical field [0001] The present invention relates to the field of network technologies, and in particular, to a device identification method and device, and a weight calculation method and device for device identification. Background technique [0002] In recent years, online shopping platforms such as Taobao and JD.com have developed rapidly. In the online shopping process, buyers and sellers complete the transaction process through account identifiers (ID, Identifier) ​​registered on the online shopping platform. The above transaction process is a completely online communication method, which avoids the appearance of natural persons, so additional information is required to ensure the safety of transactions. In addition to common information such as a user's account ID and an IP (Internet Protocol, Internet Protocol) address, a user equipment identifier (ID) is also a particularly effective information. The user device ID refers to attribute information (for example, ...
