Data Science project for Resume The first step for an interview of any project is you need Resume. You need to tell clearly about your resume.

In interviews, you will be asked questions about your project. So the second step is you need to be in a position explain about project.

The third point is you need to explain the roles you performed in your data science project. If you mention the roles correctly, then, you will have 100% chance to shortlist your resume. Based on your experience your resume can be 1 page or 2 pages.

Tokenization story you need Vault based Vs Vault-less

Image
By
The term tokenization refers to create a numeric or alphanumeric number in place of the original card number. It is difficult for hackers to get original card numbers.

Vault-Tokenization is a concept a Vault server create a new Token for each transaction when Customer uses Credit or Debit Card at Merchant outlets 

Let us see an example,  data analysis. Here, card numbers masked with other junk characters for security purpose.

Tokenization

Popular Tokenization Servers

There are two kinds of servers currently popular for implementing tokenization.
  • Vault-based 
  • Vault-less

Video Presentation on Tokenization


Vault-based server

The term vault based means both card number and token will be stored in a Table usually Teradata tables. During increasing volume of transactions, the handling of Table is a big challenge.

Every time during tokenization it stores a record for each card and its token. When you used a card multiple times, each time it generates multiple tokens. It is a fundamental concept.

So the challenge here is Table size will be increased.

Vault-less server

The recently established technology is much faster than the vault based model, where the card numbers and tokens will not be stored. Whenever it received a request, it generates a random number.

Even during de-tokenization, it just decode the random number and sends actual card number. Also possible to send numeric/alpha numeric tokens.

    Hello Srini

    Just read your article on vault -v- vaultless, this question can only be answered depending on the vault itself - was it built to be scalable? Does it store every transaction? Quite simply no it does not, but like i say it all depends on how the vault was built. Is it more secure than vaultless - definately.

      Vault-less is reversible security method that replaces sensitive data with fake data that looks and feels just like the real thing. So vault-less is advanced than Vault.
