SP7Box the "business-to-business encrypted file exchange of confidential information" by applying the highest and the latest security technology, "encryption cloud management of personal data", it is a safe information sharing application that performs such as "encrypted chat communication."In SP7Box, if you can even connect to the Internet, with anyone, anytime, anywhere, it will be able to exchange a very safe and easy data personal computer, tablet, between devices such as smartphones.Similarly even SP7Chat, it can be very safely chat between devices (conversation or data exchange).Safety reasons, it is, SP7Box and SP7Chat (hereinafter referred to as those apps) because is using SP7 key that is distributed by the SP7 ( 1). This is because it is intended to be open if it were the photos and confidential documents and personal information, such as send to put nearly impossible attache case, even if the stolen attache case is, even reaching to others by mistake, there is no SP7 key never to be opened ( 2).Also they, as directly deposit in a bank of safe deposit box, a more secure because it is stored in a data center on the Internet (= storage location of the data that professional company operated), yet at the disadvantage of the storage service of until now do not worry about peep by officials of a data center management company. In this way, This app is very high service safety against leakage of information likely to occur at the time of transmission and reception and storage of data.Also in this app, also consideration to usability, creation of the terminal settings and folder that you want to exchange the data, it also has able to perform immediately with a simple operation.Feature Standard 100MB capacity can be used. Add is also possible. (Surcharge)- Photos, videos, documents, etc. various types of files I can handle. Even I can use large size of the files.Data are stored in the cloud, data is safe even if the terminal equipment has failed.( 1) SP7SP7 a variety of equipment (personal computer, mobile terminal, home appliances, cars, such as measuring instrument) to, SP7 key with a pluripotent (encryption key, authentication key, one-time password key, special such as a key) to distribute the management It is a system that you want to.With these keys, it will be possible to safely conveniently use various services. For example, to open and close the door by holding the data using keys or exchanged is encrypted, or by car by using as a key for starting the unlocking and engine of the car door, the room key to the electronic lock so that you are able to or. In this way the application of SP7 There are infinite spread.( 2) and encryption strength by SP7 keyGenerally, the combination of the key in the 8-digit alphanumeric characters about 3 trillion ways to be used, but is (10 12 square of), in SP7, the number of degree that was further multiplied by the value each other for 1 Kyobai 1 Kyo (10 the you are using a key combination of the 64 power) is the number of significant number of computers has to be calculated over the years, it has been considered practically decryption impossible.
