I was looking at solutions to detect sensitive data using a DLP solution, from a encrypted data set being transmitted.
Although DLP can detect and block password protected files, I don't suppose it can detect sensitive PII data in encrypted data and allow files on the same basis or detect files with encrypted data in it.
I have tried considering Fully Homomorphic Encryption too but it seems that is used only for computation on encrypted data and not really for analyzing the same.
Are there any suggestions or tools that can be utilized for the same?
Ps. Just a top of my head idea: Can we design a regex to detect gibberish text (like ones that usually exist in encrypted data) ?
