The embodiment of the invention belongs to the technical field of
information security, and relates to a sensitive
data detection method, which comprises the steps of obtaining a
data type of issued data when the issued data is received, and determining whether the issued data is text data according to the
data type; when it is determined that the issued data is text data, detecting the text typeof the text data, and obtaining a
feature code corresponding to the text data; matching the
feature code with a standard
feature code stored in a
database, and determining whether sensitive information exists in the text data; when it is determined that the sensitive information exists in the text data, calculating the base sensitivity of the text data, and performing desensitization
processing onthe text data with the base sensitivity not smaller than a preset threshold value. The invention further provides a sensitive
data detection device,
computer equipment and a storage medium. In addition, the invention also relates to a
blockchain technology, and the issued data can be stored in the
blockchain node. According to the method, the identification efficiency and accuracy of private dataare improved, and the safety of personal information is protected.
