Combine hardware with software for State of the art security features. 1) Key-1 focuses on the cloud oriented database using our app and Key-1 device module to provide security features such as ability to secure lock existing application preventing misuse and providing privacy. Our app uses the Key -1 unique device ID and the cloud database in combination with the build in Key-1 electronic chip to provide the security features. 2) We provide users both safety and privacy with convenience,Key-1 can be used as an app locking software enabling user to restrict the access to existing app according to his needs. Hence, our app. provides enhanced security at a deeper lever along with the already inbuilt security functions which are only restricted to front screen locks. Rather than using the conventional security methods such as inputting passwords/secure locks, we are using the key-1 device for easy operation. Inserting and removing the Key-1 can automatically lead to enabling/disabling the security features. This avoids the hassle of repeatedly entering password for every function. 3) Small size, reduced battery consumption The PCB volume size of key-1 is roughly the size of your nail (we use the external 3.5mm standard audio jack for connectivity ) which allows various accessories such as headphones plugs to be used in combination with key-1 for added customization . 4) Personal safety application Key-1 comes equipped with a unique feature of security alarm, Removing the key-1 device from the audio jack can trigger an alarm which could be extremely helpful in unseen emergencies. Hence, our device alongside providing cell phone security can also be used for personal security.
