Write an app for iPhone & Android, and write a web application


I am looking to create an app which enables low-level communication between mobile devices, PCs, or other internet-connected devices using high frequency sound patterns. This app will provide a similar service as "Authy" or "Google Authentication" but using the technology offered by Shazam. A user wishing to login to a secure website or other area will open their app and activate a key while on the receiving end, a web application or mobile device will choose to accept or deny the user, granting or denying access. An account registry is required, and a service must be created which will provide users with a unique "key" used to interface or "authorize" with a second party, and this "key" will refresh every 15 seconds for security reasons. Please message me for any questions or concerns.

Skills: Android, Google Web Toolkit, HTML5, iPhone, Mobile Phone
