Encryption of data occurs before it is written to the storage platform; decryption occurs after it is read from the storage platform on a computer separate from the storage platform. By encrypting data before it travels over a wide-area network to a storage platform (and by only decrypting that data once it has arrived at an enterprise from the storage platform), we address data security over the network. Application data is encrypted at the virtual disk level before it leaves a controller virtual machine, and is only decrypted at that controller virtual machine after being received from the storage platform. Encryption and decryption of data is compatible with other services of the storage system such as de-duplication. Any number of key management services can be used in a transparent manner.

Systems and methods are provided for object re-identification. In many scenarios, it would be useful to be able to monitor the movement, actions, etc. of an object, such as a person, moving into and between different camera views of a monitored space. A network of cameras and client edge devices may detect and identify a particular object, and when that object re-appears in another camera view, a comparison can be performed between the data collected regarding the object upon its initial appearance and upon its re-appearance to determine if they are the same object. In this way, data regarding an object can be captured, analyzed, or otherwise processed despite moving from one camera view to another.
