In order to solve the problems of the technologies described above, disclosure embodiment provides a kind of process hiding method, and the method is applicable in process hiding program, system or device, as shown in Figure 1,
Step S101, under linux system, generates scheduler module; Wherein, the operation generating scheduler module is as follows:
#include<linux/kernel.h>//quote linux system kernel header file
#include<linux/module.h>
#include<linux/init.h>
#include<linux/sched.h>
#include<linux/list.h>
MODULE_LICENSE (" GPL "); // " GPL " specifies any version that this is GNUGeneralPublicLicense
MODULE_AUTHOR (" zxl "); // module author
Initialization first variable pid and its said target task task, and generate scheduler module module_param:
Staticpid_tpid=0; The variable of // statement pid_t structure type, wherein pid i.e. the first variable, for preserving the target process number of target process;
staticpid_told_pid＝0；
Staticstructtask_struct*task=NULL; // statement task_struct structure categorical variable, task is the said target task of this target process;
//staticstructtask_struct*old_task＝NULL；
Staticchar*mystring=NULL; // statement char pointer type variable
Module_param (pid, int, 0); // module parameter is arranged, and wherein, module_param is the scheduler module of generation;
MODULE_PARM_DESC (pid, " Thepidtohide "); // module parameter is described
MODULE_PARM_DESC (mystring, " Theprocess'sname "); Mystring is the ternary hereafter mentioned, and is used for preserving the process title of target process.
Step S102, the target process number of the target process using the first variable to hide is kept in described scheduler module;
Under linux system, after generating scheduler module module_param, can will the target process assignment of the target process run hidden being needed to the first variable, then using the first variable to be kept at needing the target process number of the target process hidden in this scheduler module.Generate scheduler module, following program can being used by the target process assignment of target process run to the first variable pid, being kept in this scheduler module to use the first variable pid by needing the target process number of the target process hidden:
MODULE_PARM_DESC (pid, " Thepidtohide "); // module parameter is described
Step S103, runs described scheduler module, and obtains the said target task of described target process according to described target process number;
Step S104, judges whether described target operation task is empty;
Because target process may can not be present in linux system always, likely run and closed, or there is abnormal closedown, therefore, be kept at needing the target process number of the target process hidden after in this scheduler module at use first variable, need to start this scheduler module, this scheduler module is normally run, and the target process of the target process hidden as required number obtains the said target task of this target process, thus by judging whether this target operation task is empty, judge that this target operation task is current whether just to run in linux system, certainly, if this target operation task is empty, this is described target operation task is current and do not run in linux system, target process also just closes naturally, then current any user can not search this target process, then can exit this scheduler module, need not again for this target process carries out arranging deliberately hiding this target process, thus reduce unnecessary operation, reduce system burden.Certainly, this scheduler module can be run by following program, and whether be that sky judges to target operation task:
Step S105, when described target operation task is not empty, preserves the target process of described first variable number with the second variable, and is zero by the first variable assignments being used for representing described target process number.
In addition, if this target operation task is not empty, this is then described target operation task is current and just run in linux system, therefore, the target process of its correspondence also runs just in systems in which, now, the second variable can be given by the target process assignment that represents with the first variable, to use the real target process number of second this target process of variable save, and be zero by being originally used for the first variable assignments of the real goal process number representing target process, like this, the process number needing the target process hidden has been all just zero, this just make user cannot again by linux system order as ps order or top order inquire this target process, more cannot modify to this target process without authorization, thus this target process is hidden, and the safety in utilization of the target process needing to be hidden can be guaranteed.

In step s 201, when unloading described scheduler module, by use described second variable save described target process number again assignment to described first variable.
When unloading this scheduler module, can by the target process preserved with the second variable old_pid number again assignment to the first variable task->pid, like this, just the process number of the target process hidden before can be reduced, so that user can carry out normal queries, then modify this target process, guarantee the normal use of user.
As shown in Figure 3, in one embodiment, described method also comprises:
In step S301, the target process title of the target process using ternary to hide is kept in described scheduler module.
When hiding this target process, also can the title of this target process and Theprocess'sname be kept in scheduler module module_param by ternary mystring as required, particularly, can be comprised by following program:
MODULE_PARM_DESC(mystring,"Theprocess'sname")。
As shown in Figure 4, in one embodiment, above-mentioned steps S201 can be performed as:
In steps A 1, obtain the system chained list of described scheduler module;
