Techniques for validating
When you think of data validation, what's the first thing that comes to your mind?
This will only help with the rest of the application because you'll be able to cross out the data as being a cause for problem in possible errors that might slip into the application.Each unique value is then used to recreate its corresponding part of the key and when all parts are present and validated, the secret is reproduced.calculating, for each share, a single value that permits each share to be independently validated from remaining shares and that permits each share to be re-assembled with the remaining shares to reform the secret; andgenerating a second equation via the CRT algorithm that produces as a second remainder a particular share's pairwise co-prime number when the CRT value is divided by another pre-established pairwise co-prime number; and, wherein calculating further includes subsequently validating a particular share from a particular user when that particular user presents a particular single value, and using the particular single value to process the first equation and the second equation to obtain a particular intermediate value and a particular share's pairwise co-prime number and then dividing the secret by the particular share's pairwise co-prime number and comparing a resulting remainder against the particular intermediate value.further comprising, invalidating the particular share when the resulting remainder does not equal the particular intermediate value, and wherein when the resulting remainder does equal the particular intermediate value delivering the secret to a requester when each of the remaining shares of the secret are presented and similarly validated., wherein validating further includes dividing each specific single value by a control pairwise co-prime number to obtain a result value that is compared to an expected validation value and when equal determining that validation was successfully achieved., wherein using further includes dividing each specific single value by a particular pairwise co-prime number associated with a particular user that supplies the specific single value to obtain a remainder and dividing each specific single value by another pairwise co-prime number to obtain a calculated pairwise co-prime number, and wherein determining that the particular user has a valid portion of the shared secret when the remainder is equal to a calculated remainder that results from dividing the shared secret by the calculated pairwise co-prime number., wherein re-assembling further includes delivering the secret from secure storage to a resource in response to policy once each portion was re-created and each specific single value is successfully validated.wherein the key dividing service splits a shared key into shares, each share corresponds to a particular user and a total number of shares is equal to a total number of the users, and wherein the key dividing service supplies a unique value to each of the users to represent each user's share, and wherein the key validation service validates each unique value and reconstructs each share from each unique value and the key validation service reproduces the shared key when each share is successfully reconstructed and validated., wherein the CRT algorithm produces three equations for each unique value, a first equation provides a particular share of the shared key, a second equation provides a pairwise co-prime that when used as a divisor to the shared key produces the particular share, and a third equation provides a control value that validates each unique value to ensure no changes have occurred., wherein the shared secret is completely reconstructed by the key validation service for each unique value but is not supplied to a requester unless the total number of unique values are received representing the total number of shares and is not supplied to the requestor unless each share is validated via each unique value.wherein the secret divider divides a secret into portions each portion corresponds to a user and each portion represented by a unique value supplied to a particular user, and wherein the secret builder receives each unique value and recreates each portion of the secret and also validates each portion and when all portions are received and validated the secret builder reproduces the secret.One of the four options we have in any problem situation is acceptance.Validation is one way that we communicate acceptance of ourselves and others. When your best friend or a family member makes a decision that you really don't think is wise, validation is a way of supporting them and strengthening the relationship while maintaining a different opinion.What this means is data validation, in order to be as successful as it can be, must be implemented at all parts that get the data, processes it and saves or prints the results.
Let's take the time and list those parts here and explain why they should be considered.
There's more to data validation that simply validating the data, alot more as you'll see there is alot of things that can be done to help in the data validation process.
In this document, we will cover all you'll ever need to know about data validation, what it really means, how to use it effectively and ultimately how to minimize the use of data validation while still assuring that the data is indeed valid. Data validation, as explained above, is making sure that all data (whether user input variables, read from file or read from a database) are valid for their intended data types and stay valid throughout the application that is driving this data.
Validation is a way of communicating that the relationship is important and solid even when you disagree on issues.
Validation is the recognition and acceptance of another person's thoughts,feelings, sensations, and behaviors as understandable. Holding someone's hand when they are having a painful medical treatment, listening with your whole mind and doing nothing but listening to a child describe their day in first grade, and going to a friend's house at midnight to sit with her while she cries because a supposed friend told lies about her are all examples of being present.
Just being present, paying complete attention to the person in a nonjudgmental way, is often the answer.
