METHOD, ELECTRONIC DEVICE, AND NON-TRANSITORY COMPUTER READABLE RECORDING MEDIA FOR IDENTIFYING CONFIDENTIAL DATA

摘要

A method, an electronic device, and a non-transitory computer readable recording medium for identifying confidential data are provided. The electronic device determines whether a data has special formats by a format feature representing the special format. Then the electronic device further determines whether the special format of the data is the confidential data by confidential factors representing the special format to be the confidential data. Therefore, the method, the electronic device, and the non-transitory computer readable recording medium for identifying confidential data can correctly provide the confidential degree for the data having many confidential descriptions but few numbers and can identify the confidential data having the special format, thereby preventing the data leakage.

1. A method for identifying confidential data, used in an electronic device, the electronic device storing a plurality of identification groups, each identification group corresponding to a special format, each identification group having a format feature representing the special format and a plurality of confidential factors representing that the special format is the confidential data, and the method for identifying confidential data comprising:
capturing one of a plurality of data and defining the data as a captured data; capturing one of the format features and defining the format feature as a captured feature; determining whether the captured data has the corresponding special format according to the captured feature in the electronic device, if the electronic device determines that the captured data has the corresponding special format, determining whether an occurrence frequency of the confidential factors corresponding to the special formats in the captured data is larger than or equal to a confidential threshold, wherein if the electronic device determines that the occurrence frequency is larger than or equal to the confidential threshold, it means that the special formats in the captured data is the confidential data, and if the electronic device determines that the occurrence frequency is smaller than the confidential threshold, it means that the special formats in the captured data is not the confidential data; and determining whether there is the format feature that is not captured among the format features in the electronic device, if the electronic device determines that there is the format feature that is not captured among the format features, capturing the format feature that is not captured and defining the format feature as the captured feature so as to again determine whether the captured data has the corresponding special format according to the captured feature, and if the electronic device determines that there is no format feature that is not captured among the format features, capturing the next data and defining the next data as the captured data so as to again determine whether the captured data has the corresponding special format.
