Epina ImageLab supports the encryption of random forest models, binding them to either a licence ID or a license group (see the section Encryption of a Random Forest Model for details).
The method SaveModel stores the RF model in encrypted bounded form. There are five different modes of encryption (controlled by the parameter Mode):
| rfemNoEncryption |
The stored RF model is not encrypted at all. The parameter Key is not evaluated and can be left empty. |
| rfemPassword |
The RF model is encrypted using a user-defined password (parameter Key). This mode is equivalent to the function SaveOnDisk. |
| rfemUserLicID |
The RF model is encrypted and bound to the license ID of the current user. The parameter Key is not evaluated and can be left empty. |
| rfemForeignLicID |
The RF model is encrypted and bound to a foreign license ID specified in the parameter Key. Please note that the specified license key must valid. |
| rfemLicGroup |
The RF model is encrypted and bound to a license group specified in the parameter Key. |
The function returns the following error codes:
0 ... everything is OK, the random forest has been stored
-1 ... cannot save the model (i.e. disk full, write protection)
-2 ... invalid License ID
-3 ... password must not be empty
