The invention discloses a data bleaching method for financial data. The bleaching method comprises the following steps: (1) submitting a data demand by a testing center; (2) recovering data from a tape library of a production environment onto a disk, and synchronously loading a data file into a database for data extraction; (3) performing data bleaching according to the data demand of the testing center; (4) after the completion of data bleaching, exporting the database into a data file, encrypting the data file, and transmitting the encrypted data file to the testing center; and (5) loading the obtained data file by the testing center. Through adoption of the method, sensitive financial business data involving personal privacy or needing to be protected in a non-production environment can be removed, shielded and transformed, and desensitization processing is performed on sensitive data, so that the aim of protecting the sensitive data is fulfilled.

Bleaching method for financial data

The embodiment of the invention provides a phone number data search and classification method. The method mainly includes the steps that a data analysis rule corresponding to phone numbers is preset, sampling data in a data table are extracted, data number data analysis is conducted on the sampling data according to the data analysis rule corresponding to the phone numbers, and phone numbers in the sampling data are found out according to the analysis result. According to the phone number data search and classification method, the data categories of the phone numbers in the data table of an enterprise application database are found automatically and effectively, key data of phone numbers in the data table of the enterprise application database are found out and classified efficiently, workload can be lowered greatly, and working hours can be shortened.

Phone number data search and classification method

According to an example aspect of the present invention, there is provided an apparatus (160, 170) comprising a receiver configured to receive anonymized sensor information, at least one processing core configured to convert the anonymized sensor information into personal sensor information based at least partly on personal information, and a memory interface configured to, under control of the at least one processing core, access the personal information.

Privacy preserving monitoring

The invention provides a method and device for privacy-protected opening and a method and device for privacy-protected data de-duplication, belonging to the technical field of communication. The privacy-protected opening method includes: receiving a request for acquiring data sent by each application; allocating a corresponding APP ID and APP Secret for each application; analyzing a data request sent by each application and acquiring a category to which the data requested by each application belongs; according to the acquired category the data requested by each application and a pre-stored mapping table between to-be-opened data and the categories, extracting the corresponding to-be-opened data; extracting sensitive fields in the to-be-opened data corresponding to each application; introducing encrypted information to encrypt the sensitive fields to obtain encrypted data; and replacing the content corresponding to the sensitive fields in the to-be-opened data with the encrypted information to obtain privacy-protected data to be open to the applications.

Method and device for privacy-protected opening and a method and device for privacy-protected data de-duplication

The invention discloses an identity authentication method and device based on a virtual number. The method comprises the following steps: S101, receiving identity information submitted by a user through a client; S102, verifying the identity information of the user by using pre-defined identity information database; S103, receiving a request for converting the user information submitted by the user through the client into the virtual number under the condition that the identity information verification of the user is passed; S104, converting the user information into the virtual number, and associating the user information with the virtual number; S105, authorizing the virtual number to the user or providing the same for the third party for performing marketing in the time-limited way; andS106, receiving an authentication request of the user, performing user identity authentication through the virtual number. Therefore, the effectiveness of the authentication is guaranteed, and the real information of the user cannot be leaked.

Identity authentication method and device based on virtual number

The invention discloses a privacy-removing processing method and a device using the privacy-removing processing method. The privacy-removing processing method comprises the following steps: extracting an index field of client privacy data obtained from a data source and calling a privacy-removing mapping relation chart; mapping the index field into mapping codes in the privacy-removing mapping chart according to the mapping rules of the privacy-removing mapping relation chart and finishing the privacy-removing process of the client privacy data. According to the privacy-removing processing method and the device using the privacy-removing processing method, a privacy-removing processing engine is designed to be arranged inside the an extract transform and load (ETL) module, on one hand, existing system resources of the ETL module is sufficiently used and occupation of system resources of a data cabin and a data mart is avoided; on the other hand, due to the fact that the ETL module is an united inlet of all data of an business analysis system, the ETL module carries out all the client privacy-removing process, and therefore uniformity of all the operations can be ensured.
