Definitions

• the invention relates to a secure method of sampling and analysis of samples.
• a crime scene sample may be used as evidence, possibly leading to the conviction or exoneration of a person under investigation. It is therefore essential to be able to certify with certainty the sampling conditions and the integrity of the sample used as evidence in order to avoid any miscarriage of justice. That is to say, it must be possible to certify with certainty that the sample used for the analysis was present at the crime scene and that it was not modified, interchanged or degraded during of his manipulation.
• the guarantee of the sampling and origin conditions of the analyzed samples may be essential. Indeed, for reasons of viability of the sample and relevance of the analysis, it is important to know the time that has elapsed between the sampling and the actual analysis of the sample. This time should be as short as possible and should not exceed the viability period of the sample.
• this warranty is based on human speech and the information provided by the person in charge of the levy. The date of the sample can therefore be questioned. Human speech can always be questioned whether people giving their word are in good faith or not.
• the guarantee of the conditions of sampling and analysis of a sample may be the issue of debate and questioning that could lead to the conviction or the exoneration of a person under investigation without that we have the certainty that the truth has been made in the file. It is therefore understandable that it is necessary to provide this guarantee in a certain and reliable way and not only by means of human speech.
• the aim of the invention is to provide a solution to this problem by proposing a secure sample collection and analysis method in which all the information relating to sampling and analysis is recorded on an inviolable support in which the sample is collected.
• the invention relates to a secure sample collection and analysis method using a sample storage device comprising an information storage means and at least one sampling container that can be associated with it, the device being equipped with means for verifying and guaranteeing the integrity of the container before and after its use when said container is associated with the device, the container comprising information storage means comprising previously identification information of said container, said method being characterized in that it comprises the following steps: a. identifying at least one person responsible for collecting and storing this identification in the information storage means of the device and in the storage means of the container; b. registration of the place, the date and the time of sampling in the storage means of the device and in the storage means of the container; vs. identification of the sampling container and storage of this identification in the storage means of the device; d.
• the step of identifying at least one person in charge of sampling and / or analysis is completed by an identification of at least one control and by storing this identification in the storage means of the device and in the storage means of the container.
• the information relating to the sampling location is provided to the storage means by a positioning device, such as a GPS, the data of which can not be distorted, and the information relating to the date and time of sampling is provided to the storage means by a clock, of the atomic clock type that can not be distorted.
• sample storage device and the sample container that may be associated with it are, for example, in accordance with the biological analysis system described in the document FR-2 787 042 and in the document FR-2 865 190 filed in the name of the applicant.
• Such an analysis system makes it possible to avoid any error in the identification of samples and to obtain automated traceability of the samples.
• the container makes it possible to visualize whether it has been brought to its integrity or not.
• the information storage means of the container are formed by an electronic tag whose contents can be read remotely.
• the storage device is provided with means for verifying and guaranteeing the integrity of the container before and after its use when said container is associated with the device.
• the integrity of the container it may be in accordance with the tube described in document FR-2 865 190 as indicated above.
• the analysis step h. may include the following steps: i. identifying at least one person responsible for analyzing and storing this identification in the storage means; j. checking the conformity of the identity of the container to be analyzed on the basis of the information contained in the remote storage means with the identity of the container handled by the person responsible for the analysis on the basis of the information contained in the storage means of said container ; k. verification of the integrity of the sampling container after its closure during sampling;
• the method may further comprise a step of printing a visual identification means which is associated with the container after its identification by the sampling device.
• the method comprises a storage step between the sampling steps and the analysis steps.
• the device is adapted to receive a plurality of sampling containers, the identification steps being repeated for each container.
• all the clues taken from the scene of a crime can be associated with the same device.
• the sampling container is associated with the device before step a. then removed from the device during step e. and then reassociated with the device during step f., the means of guaranteeing the integrity of the container after its use being applied by the device.
• a reading and data acquisition device for recording and reading information on the storage means of the device and on the storage means of the container, said member being manipulated by the person identified in said storage means.
• Such an organ is for example a laptop or an electronic pocket assistant, such as a PDA (palm digital assistant) organizer, for entering information and transmitting this information.
• PDA palm digital assistant
• Such reading and input devices are commercially available.
• the positioning device and the clock can be integrated in the reading and input device.
• the identification of the user of such a reading and gripping device can be performed by means of a biometric identification system.
• the user then identifies for example by means of his fingerprint.
• Such an identification system is also commercially available and can be easily associated with the reading and input device.
• the storage means of the device and the container may further store photographs, for example of the crime scene. One can then use a digital device sending the pictures taken on these storage means.
• the method according to the invention thus makes it possible to gather all the information relating to a sampling in a storage means irreversibly linked to the support containing these samples, which provides a guarantee on the authenticity of this information.
• Such a method can be used in all areas where verifying the authenticity of sample collection, storage and analysis conditions may be essential.
