Audio-based data management technology ("ABDM") enables computers, tablets, smartwatches and smartphones that are near each other to communicate using sound as the carrier of information that underlies the data transmission process. You can share photos, audio and video files, documents, send text messages or make secure payments. All files and messages are encrypted and securely stored in an MP3 data file, which is located both on the remote database server and on the user's smartphone, tablet or hard drive.

An MP3 data file is an artificially produced MP3 audio file that consists of two components, an audio component and a data component. The audio component of an MP3 data file is the audio signal carrier. It corresponds to the content contained in the data component of an MP3 data file and is accompanied by security tags consisting of a hash code, an IP address, a digital signature, a public key, and a timestamp embedded in that file. The same MP3 data file can be used more than once, but a new MP3 data file can also be generated upon each new use, depending on what it is used for. If used multiple times, there are several ways to treat an MP3 data file. We can use it to initiate wireless data transfer between two devices, send as an e-mail attachment, or share via messaging apps such as Viber, Whatsapp, etc.

You can store and share all types of files including, but not limited to photos, audio, video, PDF documents, XML files, or banking transactions. You don't have to use any accessories such as smart cards or point-of-sale (POS) card readers, or install any app that could potentially compromise your privacy. Only use your personal device that you carry with you every day. Whether it's a smartphone, smartwatch, tablet or computer, it will always be "ABDM-enabled".

ABDM can be used for contactless payments, creating/minting Authentic digital assets, information/data sharing, in-store checks, after-sales product experiences, access control, tracking public participants, or bootstrapping wireless connections. This technology guarantees the fidelity and security of the way data is stored and transmitted:

• It provides secure storage of sensitive user data (audio and video files, text messages, documents, bank payments etc.) within an MP3 audio ("data") file;
• It enables secure contactless data transfer process using sound as the carrier of information necessary to meet the transmission requirements;
• Only two communication devices are required for data transmission and processing; the receiving device communicates with the remote database server through the ABDM app running in a web browser.

The sound used as a carrier is an audio signal that falls within the standard hearing range. The speaker of the device emitting the signal must be brought closer to the microphone of the device receiving the signal in order to reduce the influence of ambient noise.

The audio signal carrier provides cryptographic encryption (protection) of the content of the audio data file and prevents its alteration, loss, corruption or misuse along the way. This encrypted data set and security tags, consisting of a uniquely generated hash, digital signature, IP address, public key, and timestamp, are embedded in the MP3 data file and establish reliable and secure channels for transferring files and information. An MP3 data file is considered a self-verifying part of a blockchain that operates without the need for a central authority. Instead of being locked within a single database, as is the case with centralized systems, audio and data components of MP3 data files are diversified throughout the blockchain and made available for as many computers connected to a shared peer-to-peer network as needed. Data stored on the blockchain becomes virtually immutable and can no longer be edited, replaced or removed.
