Authentication source authentication system .

Oh, simple, to give you a way, use vs2005 to make a role system, through vs2005 set a certain folder as a role view, after setting the role, you can add the members you need to add to the role, set the permissions of the folder, and put the files you need to only let insiders see into the folder.

If you can't vs2005, then I can't help it.

Another of the most stupid ways is to create a separate folder, put the files in, don't publish the folder's keylink on the web, for example: The first page of the report in the inter folder is , you only need to tell the person you need to tell the corresponding keylink of the folder.

It's simple, make a table, and enter all the people in a name field in the table.

When you log in, use the phrase select * from table where name="Enter the name of the person".

If you have it, you will let it in, and if you don't, you will not be allowed to enter.

The authorization mechanism is relatively mature.

Create a user group and specify the permissions of the user group.

For example, user Zhang San comes in and checks his group permissions, he is a premium member user group! can be viewed.

Li **Lai, low-level member user group! Do not view it.

Conducive to future expansion.

The fourth floor of the same words. Then I know the name of the insider. Then I'll enter it.

It's good to take the first method.

The problem is that people who don't have permission can not see information that they shouldn't be seeing by typing someone else's name???

It can only be said that your prevention is basically useless.

This is actually no different from asking for a password.

It's just a database verification program for logins

There are a lot of similar **.

I will, I can help you write!

The ID card verification system is a machine specially serving the second-generation ID card, which is a system that integrates ID card reading and verification.

The device adopts the internationally advanced TypeB contactless IC card reading technology, and exchanges data with the special chip in the second-generation resident ID card by wireless transmission, which can read out the personal information in the chip, and then upload this information to the computer through the computer communication interface.

The randomly provided installation software can complete the operation of reading the personal information in the ID card chip through the ICR-100M, and the random software can also decode the information into text and photos for display and storage, and carry out the identification of "identity of the person and the certificate". At the same time, the product can also provide open application programming interface (API) functions for system integrators to carry out secondary development.

What kind of server did you use to build a server? There are too many environments that can be built on the http server, and there are more types of services that can be built, and the third-party services can be described in countless ways, just write a few words that are an http server, so you have to say the type, this kind of thing is like saying that you have installed a win7 system, and what is the difference between installing a software and not making it bad?

Check whether network sharing is enabled and whether the guest user is enabled.

This situation is usually a problem with the server's remote service authentication mechanism. After installing 2008, it was normal for a period of time, but after a while, such a problem appeared, maybe the remote desktop service of 2008 was restricted. Normal use requires payment and registration.

Is the username and password wrong?

Windows authentication mode, only Windows authentication. Users cannot specify SQL Server 2000 login IDs. This is the default authentication mode for SQL Server 2000.

You cannot specify the Windows authentication mode for an instance of SQL Server running on Windows 98 because this operating system does not support Windows authentication.

Mixed mode, if a user provides a SQL Server 2000 login ID when logging in, they are authenticated using SQL Server authentication. If you do not provide a SQL Server 2000 login ID or request Windows authentication, you authenticate it using Windows authentication.

Authentication mode.

When a user connects through a Microsoft Windows user account, SQL Server uses information from the Windows operating system to verify the account name and password. This is the default authentication mode and is more secure than the hybrid mode. Windows authentication uses the Kerberos security protocol, provides password policy enforcement based on complexity verification of strong passwords, provides account lockout support, and supports password expiration.

2.Mixed mode (Windows authentication and SQL Server authentication).

Allows users to connect using Windows authentication and SQL Server authentication. Users connecting through a Windows user account can use a trusted connection that is validated by Windows.

If you choose mixed-mode authentication, you must set strong passwords for all SQL Server logins. This is especially important for SAs and logins that are the Sysadmin fixed server role.

Authentication mode.

In fact, it is the information authentication of your login to the operating system.

2 Mixed mode (Windows+SQL).

Windows-based

Hybrid authentication and SQL Server identity authentication.

1. The nature is different.

Identity authentication refers to the confirmation of a user's identity through certain means.

Message authentication verifies the integrity of a message when the receiver receives a message from the sender, and the receiver verifies that the received message is authentic and has not been tampered with. It has two meanings: verifying that the sender of the information is genuine and not impersonating, i.e., data origin authentication; Verify that the information has not been tampered with, replayed, or delayed in transmission.

2. The purpose is different.

The purpose of authentication is to confirm that the user who is currently claiming to be an identity is indeed the claimed user. In everyday life, identity verification is not uncommon; For example, by checking the other party's documents, we can generally be sure of the other party's identity. Although this practice of confirming the identity of the other party in daily life also belongs to the broad sense of "identity verification", the term "identity verification" is more often used in computers, communications, and other fields.

The purpose of message authentication is to prevent intentional or unintentional tampering with transmitted and stored messages.

3. The methods are different.

There are many methods of authentication, which can be basically divided into: shared key-based authentication, biological-based authentication, and public-key encryption algorithm-based authentication. Different authentication methods have different levels of security.

Message authentication includes message content authentication (i.e., message integrity authentication), message source and host authentication (i.e., identity authentication 0), and message sequence number and operation time authentication. It has important applications in the anti-counterfeiting of bills (such as the golden tax system of taxation and the payment cipher of banks).

The system piracy is not doing well, change to a pirated system that is doing a little better.

1) Change roaming to local

2) Remove the netbios

3) The account password could not be found, and finally the buffered login was made.

It is recommended to use win8 or , the new version of the system can give full play to the hardware advantages, and the compatibility is better and more stable!

Win7 consumes memory hardware resources, and it is an old system four or five years ago, and the compatibility and stability certainly cannot catch up with the new system.
