Definitions
- the present invention relates to a method for customizing data placed in a computer called personalization parameters, personalization allowing, station by station or user by user, that each of said data are different. Said data is, before being used, written in a medium that does not allow persistent modifications and then read efficiently from this medium.
- Non-volatile media These are the data storage media that are not always erased when the computer is shut down or started. These are for example the following media: o support set and magnetic diskettes o set support and magnetic disk (or part) o support and opto-magnetic rewritable discs o non-volatile memory (NVRAM, flash memory) o data server on a network (local network, Internet ...) - Volatile media: Data storage media is always erased when the computer is shut down or started. For example these are the RAM memories
- PP Personalization parameter
- the personalization parameters are generally taken into account by logical data management methods to customize said logical data management methods.
- logical data management methods to customize said logical data management methods.
- the following customization parameters can be mentioned: o machine account password in an authentication domain, for example "Machine Domain Account Password in Active Directory". By default this parameter changes regularly automatically without human intervention.
- o Name of the computer
- Logical process license for managing data access to a service on the network
- Parameter characterizing the fact that daylight saving time is actually applied to the computer concerned o All or part of files containing information specific to each computer, for example license files.
- the physical representation of the personalization parameters is the set of bytes that contain the value of a personalization parameter before it is read and actually taken into account. This is for example all or part of a file on a nonvolatile media, a group of sectors of data on a hard disk, all or part of an internal structure of the operating system such as one or more values in a key to the registry of "Windows"
- - Windows registry internal structure specific to operating systems of the "Windows” family whose physical representation is a set of bytes in RAM. Said physical representation is duplicated at regular intervals in several data files always located on the system hard disk by construction of the operating systems of the "Windows” family, so as to be read at a later start of the computer so to instantiate the physical representation of the "Windows" registry when it does not exist yet.
- - System hard disk data recording and reading media used by the operating system, in particular for collectively storing the files that make up the operating system and that contain the values of the parameters of the operating system operating system. These media can be partitioned and protected in whole or in part for reading and / or writing. Examples include: o Hard drives (or hard drive partitions) o Solid memories used and recognized by the operating system as hard drives, o
- Nonvolatile media Methods for making non-volatile media logically volatile. These write protection mechanisms intercept and redirect to RAM or a volatile buffer (for example a file storing the writes made during an operating system session, which file is deleted at the beginning or end of each session of the operating system. exploitation) all or part of the data whose writing in the protected nonvolatile media is requested by the operating system or by the logical application methods of data management.
- RAM or a volatile buffer for example a file storing the writes made during an operating system session, which file is deleted at the beginning or end of each session of the operating system. exploitation
- a module placed in a computer usually represented by a file or a group of sectors of a hard disk, containing instructions that a computer can execute.
- a "Master-Boot-Record (MBR)" a "boot” sector, an operating system loader are logical methods of data management.
- An operating system kernel, a device driver, are logical processes for managing data.
- a computer application contains at least one logical method of data management.
- some computers can be configured to use write protection mechanisms so that they can not sustainably store personalization type data.
- the files for launching these embedded elements of the logical data management process are generally stored on "Disk-On-Modules" or “Flash-Disk”, which are actually “flash” (nonvolatile) memory used by the computer in place of a hard disk and using a “hard disk” interface to communicate with other computer components, which fact that these flash memories are, "Logically” and for the computer, hard drives.
- flash-Disk disk-On-Modules
- Client-Light are usually set up mechanisms preventing permanent writes in the "system disk”. This is often called “Write Filters” that redirect all (usually volatile) writes to the system disk.
- First start 2. Loading the operating system kernel (the write filters are then active, making some media nonvolatile, volatile) a) Possible access to the physical representations of the personalization parameters b) Reading by the operating system of the personalization parameters (for example the parameter characterizing the fact that the system time of the computer concerned takes into account the shift induced by daylight saving time is: FALSE c) Use by the logical processes of management of personalization settings previously read 3. Manual removal of system hard disk protection by a competent and authorized operator by making the write protection mechanisms inoperative.
- New startup by a user identical to the previous one.
- the modification of the customization parameters is lost, for example the parameter characterizing the fact that the system time of the computer concerned takes into account the offset induced by daylight saving remains TRUE.
- the purpose of the present invention is to significantly simplify the updating of the personalization parameters and even allows a close or remote user to make persistent modifications of personalization parameters according to a level of authorization and the nature of the customization setting.
- said personalization and modifications of the personalized data can be performed without having to manually modify the data on the storage media accessible to said computer and normally protected against writing or without having to temporarily disable the protection mechanisms against the data. writing.
- the invention also makes it possible to make changes in the configuration of an operating system used by several computers while retaining the customizations specific to each computer, for example in the case of deployment on multiple computers. a single hard disk image, which can be deployed with logical methods of managing hard disk duplication data.
- the method according to the invention makes it possible advantageously to overcome the problems caused by these techniques and to eliminate all or part of the steps required to take into account the personalization parameters, as well as to make the modifications, sometimes automatic, permanent. some of said parameters, the selections of the parameters to be taken into account being possible.
- the invention consists of components that are logical data management methods for recovering the values of the personalization parameters from a non-volatile storage medium, for example:
- non-volatile memory of the "flash" type for example
- said components copy (write) said parameter values, at each startup, to the locations of the "logical" storage medium where they will be read by the logical data management methods. Said copy will be made before said personalization parameters are used (read) by said logical data management methods.
- This copy should therefore be able to be performed very early in the process of loading the operating system, sometimes even before the loading process has begun (we then speak of process "Pre-OS” or "Pre-Boot”) , sometimes using a buffer media, temporary and accessible extremely early in the process of starting the computer, such as the computer's RAM.
- the method according to the invention provides that on extinction (or when the operating system discharges before a restart) of the machine that uses said invention, the values of the personalization parameters are saved in a space nonvolatile storage where they will be replayed later, so as to allow their effective modification if they have to be changed or renewed for the operating system or the logical data management application processes to work properly.
- the said copy on one or more non-volatile media may even be performed during the operating system session at regular intervals, so as to retain changes in values even if the computer does not discharge its operating system in the normal way (for example in case of power failure of the computer)
- the present invention aims to overcome the major drawbacks related to the write protection of the storage media which contain the physical representation of the personalization parameters, by proposing an original and specially adapted method for taking into account and updating day of parameters for customizing a platform at the loading and initialization of at least one logical data management method, said parameters then being read on a logically volatile storage medium, that is to say which such that any modification of a value of one of these parameters made by a user or a logical data management method is lost during the stop or start procedure of said platform,
- the method according to the invention comprises the following steps: 1) First start-up 2) Loading the operating system 3) Loading the kernel of the operating system (the writing filters are initially active, making some media nonvolatile, volatile) 4) Possible access to the physical representations of personalization parameters 5) Reading by the operating system of the personalization parameters, generally read in the system hard disk (for example the parameter characterizing the fact that the system time of the computer concerned takes into account the offset induced by daylight saving time is: FALSE) 6) Use by the data management logical processes of the customization parameters previously read 7) Manual removal of the protection system hard disk by a competent and authorized operator by making the write protection mechanisms ineffective. 8) Stop
- PROG-INJ reads the value of the parameter characterizing the fact that the system time of the computer concerned takes into account the offset induced by daylight saving time, and this value is FALSE e) no action is taken if the values of the PPs do not exist and go directly to step 18 f) Recopy by PROG-INJ of the values of the previously read PPs (for example the value of the parameter characterizing the fact that the system time of the computer concerned takes into account the difference caused by daylight saving time, valaur which is FALSE) instead of the PP values that the operating system or Logical data management processes will read themselves later.
- Judgment 24 New startup by a user: identical to the previous one.
- the modification of the personalization parameters is kept as for example the value (TRUE) of the parameter characterizing the fact that the system time of the computer concerned takes into account the shift induced by daylight saving time. This value is maintained and has become logically nonvolatile.
- the method consists in creating the persistent storage of personalization parameters that would otherwise be read and "written" in a volatile data storage medium and whose modifications would consequently be lost during a restart of the station, the process according to the invention describes a method which allows the automatic taking into account and the automatic updating of the values of some of the parameters of personalization of a platform at the level of loading, initialization and extinction procedures.
- At least one logical data management method the values of said parameters being stored by default on a storage medium in a non-writable manner, that is to say that they are such that, without the use of the invention any change in the value of any of these parameters made by a user or a logical data management process is lost during the shutdown or marrage of said platform, characterized in that it consists in creating in a first step one or more insertions in one or more sequences of loading and / or initialization of (said) process (s) logic (s) ( s) data management, of at least one logical data management subprocess (here called PROG-INJ) which retrieves the value (s) of the previously duplicated customization parameter (s) ( s), each of the insertions being placed in chronological order after the previously duplicated corresponding personalization parameter (s) is (are) readable, each of the insertions being placed in chronological order after the customization parameter (s) to be modified is (are) writable,
