Dynamic Masking & Encryption offer many possibilities
Dynamic Masking is transforming the defined data subjects from the moment of leaving the source also called “encryption in motion”. The data at source remains unchanged and in the clear. The real data objects are only provided if this is necessary for the user due to his function otherwise the data remains hidden, anonymized or pseudonymized.
For the data sets with confidential information “encryption at rest” is needed to encrypt the data subject at the source and decrypt the data only if required. The data cannot get read if there is no access to the master key to decrypt the data.
