In this blog, I explain the numerous ways to identify sensitive data. The main point in this posting is to articulate the complex nature of identifying sensitive data to comply with regulation, compliance, data governance, and data hygiene practices. In scenarios such as these, the advantages of using automated tools such as "Spirion.com" to augment manual approaches is obvious.
Passports and passport cards have numerous technologies built into the process of validating a subject such as myself "Cory Retherford". Passports use numerous codes, which will discuss in the following paragraphs, watermarks, steganography, RFID technologies similar to that of certificate authorities when validating website TLS certificates "HTTPS" and other approaches ill address.
This information is not at all intended to help you create fake identities but is intended to explain the nature of how identities are secured and to inform you as a Cyber Security Expert "White Hat". For those others use TOR where the DOJ can track your bad habits.
The first two numbers indicate which passport office issued your passport or where you applied for the passport.
15, 20, 21
Z or 70
The format of the first row
P indicates a passport, C indicates a Passcard
Type (for countries that distinguish between different types of passports)
Issuing country or organization.
Surname, followed by two random characters, followed by given names.
In the name field, spaces, hyphens and other punctuation are represented by <, except apostrophes, which are skipped. If the names are too long, names are abbreviated to their most significant parts. In that case, the last position must contain an alphabetic character to indicate possible truncation, and if there is a given name, the two fillers and at least one character of it must be included.
The format of the second row is:
Check digit over digits 1–9
Nationality (ISO 3166-1 alpha-3 code with modifications)
Date of birth (YYMMDD)
Check digit over digits 14–19
Sex (M, F or < for male, female or unspecified)
Expiration date of passport (YYMMDD)
Check digit over digits 22–27
Personal number (may be used by the issuing country as it desires)
Check digit over digits 29–42 (may be < if all characters are <)
Check digit over digits 1–10, 14–20, and 22–43
U.S. Passport numbers must be between six and nine alphanumeric characters (letters and numbers).
The "C" that precedes a U.S. Passport Card number is no longer case sensitive.
If you have ever been to the airport or through customs, TSA first visually and/or scans the MRZ of the passport. This printed info contains the basic access control keys needed to "unlock" the embedded chip.
Other nations such as India and the Maldives for example first digit is alphabetic and the remaining seven digits are numbers.
