Did you know that over 80% of data breaches are caused by weak or stolen credentials?

Today is a data driven world, our personal information is increasingly vulnerable, the need for robust privacy measures has never been more critical. As we transition into Web3, where digital identities play a pivotal role, safeguarding sensitive information like mobile numbers is essential for maintaining user trust and security. This is where Ultimate Digits steps in, utilizing cutting-edge techniques such as salting and hashing to protect your mobile number on-chain. By transforming your mobile number into a secure digital identifier, Ultimate Digits not only enhances privacy but also simplifies the user experience in an increasingly complex digital landscape.

The Ultimate Digits Hashing Rule

At Ultimate Digits, the process of securing mobile numbers begins with a set of preliminary steps designed to normalize and prepare the data for hashing. Here’s how it works:

Preliminary Steps

1. Normalization: The first step is to normalize the mobile number by removing any spaces and stripping non-numeric characters. This ensures that the data is clean and consistent for processing.

2. Consistent Formatting: Since Ultimate Digits caters to an international audience, mobile numbers are formatted in their full international version. For instance, the number "+1 123 456 7890" is transformed into "11234567890" for uniformity.

Extraction of Ultimate Digits

Next, the system extracts the last n digits from the normalized mobile number, where n is a predetermined value (commonly set to 4). These extracted digits are referred to as the "Ultimate Digits." For example, from the number "11234567890," the Ultimate Digits would be "7890."

Salting

To enhance privacy further, the Ultimate Digits are combined with a unique user-specific salt. This salt can be derived from the user’s crypto address or another unique identifier. This process of salting ensures that even if two users share the same Ultimate Digits, their resulting hashes will be different. The salted value is computed as follows:

SaltedValue=Ultimate Digits+Salt\text{SaltedValue} = \text{Ultimate Digits} + \text{Salt}SaltedValue=Ultimate Digits+Salt

Hashing

Ultimate Digits then utilizes a cryptographic hash function to hash the SaltedValue. For this purpose, the keccak256 hash function is employed, a standard in the Ethereum ecosystem. The resulting hash is called the UltimateDigitsHash:

UltimateDigitsHash=keccak256(SaltedValue)\text{UltimateDigitsHash} = \text{keccak256}(\text{SaltedValue})UltimateDigitsHash=keccak256(SaltedValue)

Storing on the Blockchain

The generated UltimateDigitsHash is then securely stored on the blockchain. This hash serves as a verifiable proof of the mobile number without ever exposing the actual number itself.

Verification

When users wish to verify or update their mobile number, they undergo the same hashing process. The newly generated hash is compared to the stored hash on-chain to confirm a match, allowing users to retain control over their information.

Implementation Example

Let’s illustrate this with a practical example. Suppose a user has the mobile number "11234567890" and their Ethereum address (used as a salt) is "0xabc...123".

1. The last 4 digits (Ultimate Digits) are "7890".

2. The salted value becomes "7890abc...123".

3. Hashing this salted value with keccak256 yields the UltimateDigitsHash.

4. Finally, this hash is securely stored on the blockchain.

Conclusion

By employing the mechanisms of salting and hashing, Ultimate Digits offers a powerful solution for protecting user privacy in the Web3 landscape. The process not only secures sensitive mobile numbers but also enhances user confidence in the safety of their data. As we navigate the complexities of digital identity, innovations like those at Ultimate Digits are vital in ensuring that privacy and security remain at the forefront of our digital interactions.
