- the phase of treatment of the areoles may be characterized by a treatment duration of between thirty seconds and one minute and half, being notably substantially equal to one minute, and by a number of flashes approximately equal to ten, being in particular between seven and thirteen.
- the time interval between the end of the treatment of the torso portions and the beginning of the treatment of the areola breast may be provided by the standard treatment model being between one and two minutes.
- each phase corresponds to the values of the standard treatment model for each part of the torso.
- the phases 111 and 112 are thus determined as corresponding to the treatment of the left part and the right part of the torso.
- the phase 113 with a different phototype, as visible in FIG. 6c, has a duration and a number of flashes corresponding to the values of the standard treatment model for the mammary areoles mentioned above.
- Phase 110 does not correspond to the values of the typical treatment model associated with the reported treatment. This phase 110 thus corresponds to a treatment that the operator or user has not declared, implying a loss of money for the manager of the beauty center.
- Figures 9 and 10 are records of treatments reported as half-leg hair removal treatments.
- each half-leg is divided into four sub-zones and each of these sub-zones is treated successively.
- the treatment of a sub-area consists for example in applying the gel, emitting light pulses and removing the gel.
- the following sub-areas can be successively treated: the right quarter of the half-leg right, the left front quarter of the right half leg, the left right quarter of the left half leg, the left front left quarter of the left half leg, the right quarter right quarter, the left back quarter the right half-leg, the right-back quarter of the left half-leg, and the left-back quarter of the left half-leg.
- the standard treatment model for this first approach to the treatment of half-legs can be characterized by a total treatment time of between 25 and 35 minutes and a number of emitted flashes between 300 and 400.
- Each of the eight phases is for example characterized by a duration of between one and two minutes and a number of flashes issued between thirty and fifty.
- the time interval between two phases is for example between thirty seconds and three minutes.
- FIG. 9a shows eight phases 120 to 127 whose duration and the number of flashes per phase are in accordance with the values of the model of standard treatment of the half-legs according to the first approach. It is concluded that the records in Figures 9a and 9b are consistent with the treatment that was reported.
- each half-leg is divided into only two sub-areas, so that the treatment comprises only four phases carried out successively.
- the front face of one half-leg, the front face of the other half-leg and then the rear face of each half-leg are first treated after having returned the treated person.
- the standard treatment model for this second approach to the treatment of half-legs can be characterized by a total treatment duration of between 25 and 35 minutes and a number of emitted flashes between 300 and 400.
- Each of the four phases is for example characterized by a duration of between one and seven minutes and a number of flashes issued between fifty and one hundred and twenty.
- the interval between two phases is for example between thirty seconds and five minutes.
- FIG. 10a shows four phases 130 to 133 whose duration and the number of flashes per phase are in accordance with the values of the standard treatment model of the half-legs according to the second approach. It is concluded that the records in Figures 10a and 10b are consistent with the treatment that was reported.
- FIG. 11 schematically shows steps of an example method according to the invention in the context of the use as a light sensor of a camera with a reduced number of pixels, for example 10 ⁇ 10 pixels.
- the method can involve the recording of the images of this camera, which can by processing and reduced visualization of these images to verify that the user has not attempted to change the field of view of the sensor, and therefore to detect a possible fraud.
- the recorded images can be processed so as to determine firstly the nature of the flashes, their duration and / or their spectrum, and also provide a time history allowing a management of the nature of the flashes and the temporal history that can allow the detection of a fraud.
- Figure 12 schematically describes other steps of an exemplary method according to the invention.
- the time history of the flashes as well as the knowledge of the configuration of the flashes, in particular of the energy and their duration, even of their spectrum, makes it possible to check the correlation with predefined treatment models, in order to detect the type of treatment supposed to match the flashes observed.
- the difference between the treatment model that is supposed to be detected and the treatment model as declared allows to verify that the declared treatment corresponds to reality. If there is a discrepancy between the reported treatment and what is detected, it can be determined whether the difference between what has been observed and what should have been detected in the case of a non-fraudulent declaration is greater than an error threshold. predefined. If not, the treatment model is adjusted. If yes, a message indicating a high probability of fraud is issued.
