Daniel_Stuckey writes: Lockbox, a tech startup founded in 2008, just received $2.5 million in seed funding for its end-to-end encryption cloud service, Client Portal. So, how does end-to-end cloud encryption work? Lockbox encrypts and compresses files before they are uploaded to the cloud. Only a person in possession of the corresponding key can unlock, or decrypt, the files. This means that the NSA, malicious hackers, business competitors, and even crazy girlfriends and boyfriends won't be be able to peer into users' most sensitive and private files.
