Privacy Policy | 2. Notices

Some jurisdictions require the 4thTech Consortium to supply statutory notices regarding your Personal Data. These notices can be found at, including GDPR special notices.

Privacy Policy | 3. What we collect

*4thTech Consortium declares that has no access to your data with the exclusion of public keys, except in the FOURid (i.e., digital identity protocol) identification process, where you input your credentials to connect with X.509 digital certificate.
*In the case of X.509 digital certificate connection, FOURid collects your name and tax number to connect to the EU digital identity servers.
*FOURwaL does not collect any user data, it only requires permission to read and write from
*We may use cookies or similar technologies to analyze trends, administer the website and gather demographic information about our user base as a whole. Users can control the use of any cookies at the individual browser level.
*We will never ask you to share your private keys or wallet backup JSON file!

Privacy Policy | 4. Security of the Collected and Processed Information

Your chosen password is encrypted off-chain and never shared with our servers. 

FOURdx, FOURid off-chain databases;  
The 4thTech system contains three databases; (1) MySQL database: storing user first name, last name, tax number (i.e., the data needed for digital identity verification using X.509 digital identity certificate standard), platform settings, user wallets, RSA public key for data file encryption. MySQL database is protected with a firewall. Data exchanges are protected with an HTTPS connection. In the case of a user request, it is possible to delete any user-related data: (2) local or cloud file repository: storing encrypted electronic data files. In the case of a user request, it is possible to delete any user-related data; (3) blockchain: storing data file URLs (links), data file content hash (SHA-256), timestamp of the sent data file, timestamp of the read data file.

FOURdx, FOURid blockchain databases; 
4thTech utilizes advanced encryption standards (i.e., AES), with a combination of RSA encryption and hash algorithm 256 (i.e., SHA 256) to secure immutable blockchain electronic data file exchange. The electronic data files are encrypted with a symmetric algorithm (i.e., AES), as the asymmetric algorithm (i.e. RSA) is used to encrypt the symmetric key and initialization vector (i.e. IV) with the public key of the receiver. 4thTech encryption design does not allow an attacker to infer relationships between segments of the encrypted message. SHA 256 is defined as one of the most secure ways to protect digital information. SHA 256 is a mathematical process that generates a 256 bit (64 characters long) random sequence of letters and numbers (hash) out of any input. Secure hash algorithm 256 is used to calculate the file content hash value when executing a blockchain electronic data file exchange transaction via smart contract.

Privacy Policy | 5. Accessing, Updating, Correcting & Deleting your Information

You may access information that you have voluntarily provided through your account on the platform, and review, correct, or delete it by sending a request to [email protected]. To ensure GDPR compliance, the FOURwaL and FOURdx do not store any personal data on the blockchain. The data is stored off-chain. The protocol records links to encrypted files and hashes of the encrypted content on the blockchain. The hashing of exchange data enables the GDPR compliance, for example, if there were a request to delete some electronic data or documents, the network controller would be able to delete the requested data from off-chain storage, leaving what would then become an empty hash on-chain.
