#How to securely store and wirelessly share sensitive information and files
Audio-based data management technology ("ABDM") enables computers, tablets, smartwatches and smartphones that are near each other to securely store and wirelessly share sensitive data or other data that require authentication.
This technology uses sound as the carrier of information that underlies the transmission process.
You can share photos, audio and video files, documents, send text messages or make secure payments.
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".
#There is no possibility of compromising sensitive user data
Photos, audio and video files, documents, text messages, XML files etc. 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 consisting of two components, an audio component and a data component.
The audio component of an MP3 data file is a uniquely generated 5-frequency sequence that lasts a total of 3 seconds, which sounds like a beep.
It serves as an audio signal carrier that allows data to be transferred from device to device.
The data component of an MP3 data file corresponds to the content embedded in the data file.
This content includes text messages, photos, audio, video, documents, bank payments or any other file or information. It is accompanied by security tokens consisting of hash code, IP address, digital signature, public key and timestamp embedded in that file.
The data is transmitted by simultaneously reproducing sound on one device and recording on another. Once recorded, the audio file is uploaded to the remote database server for further processing and interaction with the data component of the corresponding MP3 data file.
Even if an audio signal is intercepted during transmission, users are not exposed to any risk, as such a signal does not contain sensitive user data that could be compromised.
#Cryptographic encryption and security tokens
The frequency sequence provides cryptographic encryption (protection) of the content of the MP3 data file and prevents it from being altered, lost, damaged or misused along the way.
Each MP3 data file contains its own hash, public key and digital signature to verify the integrity of the file, as well as the IP address of the file owner and a timestamp to identify when the file was created.
Without these security tokens, it is impossible to complete the process of verification of the data attached to an MP3 data file.
#The core features of ABDM data storage and transmission
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.
All that is needed are two communication devices 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, so the devices must be close to each other and prevent background noise from impairing the quality of the recorded sound.
ABDM does not collect personal data from your devices.
Both your privacy and the privacy of your data are fully guaranteed.
DCCT-based algorithms guarantee the fidelity and security of the way data is collected and transmitted. Sound acts as the carrier of information that underlies the transmission process and is transferred from device to device, as well as to and from a remote database server. It does not contain sensitive data and cannot be compromised.
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.
It enables two-way wireless communication with one device (smartphone, computer, tablet, smartwatch, etc.) as an audio/data transmitter and another device as a data receiver/processor.
Both devices can play and record audio while communicating at the same time.
The speaker of the device emitting the audio signal must be as close as possible to the microphone of the device receiving the signal to reduce the impact of ambient noise.
This technology can be used to pay for items in a store, withdraw money from cardless ATMs, create/mint Authentic digital assets, information/data sharing, in-store checks, after-sales product experiences, access control, track public participants, or bootstrap wireless connections.
The innovative process of recording and encrypting data within an MP3 audio file allows ABDM users to securely store and transfer sensitive and confidential information, files and messages from device to device.
Over time, the ecosystem has been expanded with apps and services aimed at preserving data authenticity and content integrity, improving blockchain technology algorithms, providing secure channels for financial transactions, access control, copyright protection and more.
As our company strictly takes care that the technological solutions we provide are in line with the recommendations on nature conservation through protection, conservation and restoration of biodiversity, ABDM is claimed to have no harmful effects on ecosystems or the environment. You do not have to order plastic cards to use ABDM, nor do you need additional exploitation or consumption of any environmentally harmful material.
