Hi,

We would like to encrypt JPEG images, taken from a vision control system, and store them in the harddrive for later consultation by an authorized personnel. Our production control software is written in vb 2008. is there a way we could do that?

beside encrypting images, we tought we could store the images in a SQL Server 2008 Express database. Each images are about 120K. There will be 28 images per inspection. About 500 inspections daily and we need to keep a 30 days history in the database. Is it possible?

thanks for your time and help

SQL Server Express has some limitations (listed) below.  I think the only one that may affect your application is the 4GB of storage size (per database).

    SQL Server Express supports 1 physical processor, 1 GB memory, and 4 GB storage

I'd use AxCrypt and then just store the image's location (path) in your database.  Then you can just have code encrypt and store the images (and update the database with the locations).  Additionally, the code could retrieve and decrypt the images for viewing.

This should help with the scripting (automating the encrypt/decrypt) stuff.
