Use cases

    The xCoreDisk architecture can be used in different scenarios to protect sensitive or secret data.

Simple use on a single PC

    Creating a virtual disk on a PC without having to share data will have a similar situation to that illustrated in the following image.

    In this configuration the data is saved in the form of encrypted blocks in a folder on the PC's hard disk and only the presence of the xCoreDisk device will allow you to see the virtual disk with the decrypted data.

Use in a cloud service

    We are now all used to using cloud services to store our data. It may be convenient in this case that the folder representing the virtual disk and containing the encrypted files is placed within this cloud service.

     This configuration offers several advantages:

  • the folder that represents the virtual disk and that contains always and only encrypted files will be constantly backed-up in its encrypted form: the data will not run any risk even if saved in the cloud
  • the folder in question (and therefore the virtual disk) will be easily shared between multiple PCs or between multiple users: it will be possible to use one's virtual disk in the office, return home in the evening and find everything updated also on other computers.

     The following image shows the case in which the DropBox service is used: the same configuration can be applied to any other cloud storage service to be used.

Data saved on NAS (Network Attached Storage)

     Data storage is often performed by one or more NAS units (Network Attached Storage). In this case it will be sufficient to place the folder representing the disk on the NAS: it can be backed-up without any particular precaution together with all the other data present in the NAS itself.

Sharing the virtual disk on the network

     The virtual disk created by xCoreDisk is managed by the operating system as a normal disk drive: it can therefore be shared on the network  allowing access to clear data to all enabled clients.

     The following image shows the case in which the xCoreDisk device is inserted in a server machine that shares the virtual disk with the decrypted data on the network, making them accessible to the 3 clients present.

    It is also possible to place the folder containing the encrypted data on a NAS, as shown in the diagram below.
