As a clearinghouse without intermediaries, the blockchain is revolutionary. Its operations are guaranteed to be legitimate. It is said (and it is likely true) that Bitcoin has never been hacked. Think of the blockchain as a ledger in which a community of users records their transactions and which they consult for a trustworthy record of everything that has been done.
What does this have to do with security and mobile devices? Blockchain is a way to organize collaboration without intermediaries. If verification/authentication is the key to trust, then blockchain solves the problem. It is easy to see how automatically verified collaboration can greatly help secure mobile devices, and to see the existing limitations. Authenticity plays a critical role in a mobile security strategy, but it is neither a universal nor an exhaustive solution.
A good place to start is probably by registering the netherlands whatsapp data at the time of sale or even immediately after its creation. This can be done using the unique identifiers that mobile devices already have. The registry can then track changes in ownership, as well as the scope or applications for which the device is authorized. The same identifier can be registered across social networks, manufacturers, banks and financial institutions, even geographic sub-registries.
Blockchain can also verify the sources of mobile apps and software updates, and even ensure that the cloud or data center is using the correct version of the client software to process mobile transactions. What blockchain can’t do is protect a device from exploit-based malware that gets in through a trusted app like a browser. Nor can it prevent apps from being downloaded and modified to bypass the protections that blockchain provides.
In short, blockchain is an important element of the mobile security ecosystem, but one that needs to be integrated into the ecosystem and properly developed. Today, users need to do some work to create the ecosystem themselves.
