But he added that simply securing the content of communications is not in itself enough.
However, few techniques are reported for securing the content of halftone images, although a variety of schemes have been developed for continuous-tone image encryption in literatures.
"The growing part of the business is around being able to secure the content in a digital locker.
To secure the content and still be capable enough to provide the cloud services, many homomorphic encryption based schemes are being proposed in the literature.
And several sources describe difficulties on Apple's part securing the content that would be necessary to make their device worthwhile.
Some recent works explored a new way of securing the content, named, partial encryption or selective encryption, soft encryption, perceptual encryption, by applying encryption to a subset of a bitstream.
They have diagrams where they have responsibility to secure physical infrastructure, but ultimately it's the customer's responsibility to secure the content, applications and firewall settings," Badhwar explained.
"They have diagrams where they have responsibility to secure physical infrastructure, but ultimately it's the customer's responsibility to secure the content, applications and firewall settings," Badhwar told TechCrunch last year.
Bäcklund says that its technology makes it very simple to expand geographically and efficiently, and it is now that it has managed to secure the content relationships to take the service to new markets.
Plus, it offers a new way of securing the content in apps – if someone who was not you gained access to your phone and was able to unlock it, all the apps could be locked down automatically simply because that person, as determined by the software, was not you.
