Description

  The present invention relates to a user login technique, and more particularly to a technique for reducing a login load.

  In recent years, from the viewpoint of information leakage countermeasures, a virtual PC type thin client system has been attracting attention, which virtualizes all OSs, applications, data, etc. of PCs (Personal computers) and consolidates them on a server and does not store any data in the PCs Yes.

  Generally, when attempting to log in to an information processing apparatus such as a PC, the information processing apparatus requests authentication information such as a user ID and a password from the user.

  When the authentication information matches the contents registered in advance in the information processing apparatus, login is permitted and the user can use the information processing apparatus.

  At the time of logging in to the PC, processing for reading setting information for each user stored in the user profile into the system, automatic application startup processing, and the like are performed.

  At the time of logout, processing such as saving of data used in the application, termination of the application, saving and unloading of the user profile is performed.

  In general, a recent OS (Operating System) has a function that allows a plurality of users to log in at the same time, whether it is a server or a PC (client). For example, a secondary logon function of Microsoft Windows is known for a client OS.

  On the other hand, in general, many applications created for the client OS do not support the operation on the server OS, and the client OS does not support the secondary logon function, or are often limited. In this regard, in a virtual PC thin client system that virtualizes PCs and consolidates them on a server, it is strongly desired that software on the PCs can be operated as they are.

  In addition, when a relatively large number of PCs are aggregated on a server, such as a virtual PC thin client system, if a user attempts to log in to a PC during the same time period, for example, at the start time of a company, the login process It is known that there is a problem that the load on the server increases due to the concentration of the server.

  In other words, since each user tries to log in intensively in a relatively short time, authentication processing, user profile reading processing, application startup processing, etc. overlap, which puts a burden on the server and delays the processing. A problem occurs. Further, since the processing is delayed, there arises a problem that the user who stands by is stressed.

  Until the virtual PC is prepared for startup, it is generally easy to level the load by a method such as pre-deployment in a scheduled manner. However, the trigger for login and logout depends on the use of the user. In particular, companies tend to have an unavoidable tendency for logins to concentrate and the load to rise when multiple employees start their work on time, and this reduction is an issue.

  On the other hand, logouts are distributed depending on the convenience of individual users as compared to logins, so they tend not to be treated as such issues.

  For example, Patent Literature 1 discloses a technique for storing necessary information in a high-speed storage device such as a cache memory in advance in order to solve the problem that login is concentrated and the load increases.

  Further, as a method for reducing the load of reading a user profile, examples of dynamically reading and linking a user profile when it is necessary have been proposed by Citrix, VMware, Microsoft, and the like. However, this is not a method of reducing the opportunity and amount for reading the user profile.

  Further, for example, Patent Document 2 discloses a method of processing login in advance by detecting or predicting user behavior.

  Patent Document 3 discloses a technology that preferentially allows login when the server stores information on waiting for login and waiting user so that the user can log in again.

  As a related technique, Patent Document 4 discloses a technique for allocating detected input / output devices to any virtual machine.

  In recent years, there has been known a means for utilizing storage using a semiconductor memory as a storage device, such as an SSD (solid state drive), but it has a capacity larger than that of a storage using an HDD (hard disk drive). There is a problem that the unit price per capacity is low. For this reason, the techniques disclosed in Patent Document 1 and Patent Document 3 have a problem in terms of cost.

  Moreover, although the technique disclosed in Patent Document 2 has the effect of reducing the concentration of login and the load on the server, it does not reach the effect of leveling out or the effect of eliminating the login load itself. In order to perform detection and prediction, there is a problem that it is necessary to add an apparatus or a system.

  In order to clarify the above and other objects, features and advantages of the present invention, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In addition to the above-described object of the present invention, other technical problems, means for solving the technical problems, and operational effects thereof will become apparent from the disclosure of the following embodiments. In all the drawings, the same reference numerals are given to the same components, and the description will be omitted as appropriate.

(First embodiment)
In the present invention, a function of monitoring a logout request to the OS of the PC and canceling the logout, and a function of presenting a pseudo logout state in which the PC is locked while the login session and the load of the user profile are held without performing the logout completely. Is applied to the OS of the PC to reduce the load generated during logout and re-login.

  When a logout request to the OS occurs, the logout request monitoring unit of the software detects it, terminates the running application, saves the user profile, cancels the logout process, and retains the user profile and login session In this state, a pseudo logout state is presented to the user by prohibiting and locking subsequent user operations and screen browsing.

  At the time of a re-login request, the log-in request processing unit of the software confirms whether the pseudo-logout user and the user who has requested the log-in match based on the authentication information. If they match, the pseudo logout state is canceled. If necessary, an application that is set in advance to automatically start at login is automatically started. If they do not match, the log-in process of the user who has logged out is performed after the log-out process of the user who has been pseudo-logout.

  Although the pseudo logout state looks like a logout state for the user, the logout is not actually performed. Therefore, the load caused by the saving / reading processing of the user profile for logout and re-login is unchanged without changing the user experience. Can be reduced.

  In general, the OS provides a mechanism called a hook that can add user-specific processing to a specific location. For example, Windows has disclosed technologies such as a message hook and an API hook. Since the technique may be used for monitoring the logout request in the present invention, the description thereof is omitted.

  In addition, the OS login and authentication methods can be replaced with user-specific processing or customized. For example, Windows uses replaceable modules called GINA and Credential Provider. Technology is known. Since the technique may be used for the login request and authentication processing in the present invention, the description thereof is omitted.

  Load generated when logging out and re-login by applying software having a function of monitoring a logout request to the OS and canceling the logout, and a function of providing a pseudo logout state and an authentication interface to the OS of the PC Reduce.

  Next, a first embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing the configuration of the information processing apparatus 10 according to the first embodiment of the present invention.

  Referring to FIG. 1, the information processing apparatus 10 includes a pseudo logout processing unit 110, a login request processing unit 120, and an OS 130.

  The pseudo logout processing unit 110 includes a logout request monitoring unit 111, a pseudo logout execution unit 112, and a pseudo logout cancel unit 113.

  The logout request monitoring unit 111 has a function of detecting a logout request by a user operation. Further, the logout request monitoring unit 111 has a function of notifying the pseudo logout execution unit 112 of the logout request when detecting the logout request.

  Upon receiving the notification from the logout request monitoring unit 111, the pseudo logout execution unit 112 executes pseudo logout. Specifically, first, the pseudo logout execution unit 112 ends the running application and saves the user profile. Next, the pseudo logout execution unit 112 cancels the logout process generated by the user operation. In this process, the OS is instructed to cancel the logout process.

  After that, the pseudo logout execution unit 112 locks the user profile and the login session so that subsequent user operations and screen browsing cannot be performed while the user profile and the login session are held. As a result, although the logout process is canceled, the user recognizes that the user is in a logout state in appearance.

  The login request processing unit 120 has a function of confirming whether or not the pseudo-logout user and the login-requesting user match in the login request after pseudo-logout. Further, the login request processing unit 120 has a function of notifying the pseudo logout canceling unit 113 when the user matches.

  Further, the login request processing means 120 makes a log-out process of the log-out user and a log-in request when the log-out user and the log-in request user are different in the log-in request after the log-out. It has a function of requesting the OS 130 for user login processing.

  The pseudo logout cancel unit 113 has a function of canceling the pseudo logout state. At this time, the pseudo logout cancellation unit 113 automatically starts an application that is set to be automatically started at the time of login, if necessary.

(Description of the operation of the first embodiment)
Next, the operation of the information processing apparatus 10 according to the present embodiment will be described in detail with reference to the drawings.

  FIG. 2 is a flowchart showing the pseudo logout operation of the information processing apparatus 10 according to this embodiment.

  Referring to FIG. 2, first, when a logout request is generated by a user operation (step S201), the logout request monitoring unit 111 of the pseudo logout processing unit 110 detects and notifies the pseudo logout execution unit 112 (step S202).

  Next, the pseudo logout execution means 112 terminates the running application and stores the user profile (step S203), and then cancels the logout process (step S204). Then, in a state where the user profile and the login session are retained, a pseudo logout state is presented to the user by locking so that subsequent user operations and screen viewing cannot be performed (step S205).

  FIG. 3 is a flowchart showing an operation when a login is requested in the pseudo logout state.

  Referring to FIG. 3, first, when a login request is generated by a user operation (step S301), the login request processing unit 120 matches the pseudo-logout user and the user who requests the login based on the authentication information. It is confirmed whether or not to perform (step S302).

  Next, when the users match (step S303 “YES”), the login request processing unit 120 notifies the pseudo logout cancellation unit 113 to that effect (step S304).

  The pseudo logout cancel unit 113 that has received the notification from the login request processing unit 120 cancels the pseudo logout state (step S305). At this time, the pseudo logout cancellation unit 113 automatically starts an application that is set to be automatically started at the time of login, if necessary.

  If the users do not match (step S303 “YES”), the login request processing unit 120 requests the OS 130 to perform logout processing of the user who has been pseudo-logged out and login processing of the user who has requested login (step S306).

(Effects of the first embodiment)
According to the present embodiment, a function of monitoring a logout request to the OS of the PC and canceling the logout, and a pseudo logout state in which the PC is locked without performing the logout completely and retaining the login session and the user profile. By having the function of presenting, it is possible to reduce the load generated during logout and re-login.

  Here, a minimum configuration capable of solving the problems of the present invention is shown in FIG. When the information processing apparatus 10 makes a logout request by the user, the logout process is canceled, and the user operation and the screen viewing are locked while the login session is held, and the information processing apparatus 10 is simulated. Pseudo logout execution means 112 for creating a logout state, and a login request process for confirming whether or not the user who has made a pseudo logout matches the user who has made the login request when there is a login request from the user after the pseudo logout The log-in request processing means 120 includes a log-out process for a pseudo-logout user and a log-in process for a user who has made a log-in process when the user who is logging out is different from the user who is logging in. By requesting OS 130 to It is possible to solve the problem of the present invention.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.

  FIG. 4 is a block diagram showing a configuration of a virtual PC thin client system 1000 according to the second embodiment of the present invention.

  Referring to FIG. 4, the virtual PC thin client system 1000 includes a virtual PC server 20 (20-1 to 20-l), a thin client terminal 30 (30-1 to 30-k), and a connection broker 40. Prepare. k and l are arbitrary integers.

  The virtual PC server 20-1 includes virtual PCs 201 (201-1 to 201-n) and virtualization infrastructure software 202. Here, n is an arbitrary integer. The other virtual PC servers 20-2 to 20-l have the same configuration, and each virtual PC server 20 may have a different number of virtual PCs 201.

  Since the internal configuration of the virtual PC 201 is the same as that of the information processing apparatus 10 shown in the first embodiment, the details are omitted.

  The connection broker 40 has a function of efficiently selecting the virtual PC 201 assigned to the user, and manages the virtual PC 201, the thin client terminal 30, and the user in association with each other.

  When a user who has logged in to the virtual PC 201 via the thin client terminal 30 makes a logout request from the virtual PC 201, the virtual PC 201 performs pseudo logout, as in the operation of the information processing apparatus 10 described in the first embodiment. It becomes a state. At this time, the connection broker 40 manages the information of the user who has logged out pseudo and the virtual PC 201. The management may be performed using a management table or may be another method.

  When login to the virtual PC 201 is requested from the thin client terminal 30 in the pseudo logout state, whether or not the login request processing unit 401 included in the connection broker 40 has made a pseudo logout from the virtual PC 201 before. Confirm.

  If the user who made the login request has previously pseudo-logged out from the virtual PC 201, the user is reconnected to the virtual PC 201 and is guided to cancel the pseudo-logout. Since the pseudo logout canceling operation is the same as that of the first embodiment, the description thereof is omitted.

  On the other hand, if the user who made the login request has not pseudo-logged out from any virtual PC 201 before, the virtual log-out state of the virtual PC 201 is preferentially selected from any of the virtual PCs 201, and the pseudo-logout user After performing the logout process, the login process of the user who has requested login is performed. As a result, even when the virtual PC 201 is depleted and one of the virtual PCs 201 must be logged out, a user can be efficiently allocated to the virtual PC.

(Effects of the second embodiment)
According to the present embodiment, when a connection broker preferentially selects and assigns virtual PCs in a pseudo logout state, the virtual PC is full, and one of the virtual PCs must be logged out In this case, it is possible to efficiently assign users to virtual PCs.

  Further, according to this embodiment, when a virtual PC is shared in a virtual PC thin client system, logout / login occurs every time a user using the virtual PC changes. According to this, when the user is changed, it is only necessary to prohibit (lock) the saving of data used by the user, the termination of the application, the saving of user profile data, and subsequent operations until the user profile is unloaded or logged out. Is no longer needed.

  In addition, according to the present embodiment, logout is performed in a pseudo manner so that the user profile is not unloaded or reloaded. Therefore, even if the number of virtual PCs connected and used at the same time is large, the load can be reduced and the user can be reduced. It can be expected to reduce stress.

  Next, a hardware configuration example of the information processing apparatus 10 of the present invention will be described with reference to FIG.

  Referring to FIG. 6, the information processing apparatus 10 of the present invention has a hardware configuration similar to that of a general computer apparatus, and includes data such as a CPU (Central Processing Unit) 801 and a RAM (Random Access Memory). The main storage unit 802 used for the work area and data temporary save area, the communication unit 803 that transmits and receives data via the network, the input device 805, the output device 806, and the storage device 807 are connected to transmit and receive data.
