If you want to secure private photos and videos, there are a number of options available. One of the most popular solutions is to use a password or pattern to protect the files, and this is what Gallery Lock – Safe Photos, Videos and Contacts is based on.

This is a free application that allows you to hide pictures, videos, and contacts from your phone. You can use the app to lock down your personal photos, videos, and contacts, and the files will only be accessible by you when you enter the right password or pattern.

You can import pictures and videos from your device or from the Internet, and you can import contacts as well. Once the import is complete, you can hide the files and keep them safe. You can even delete them from the device if you want to, but be careful as the files will stay in the memory of the device.
