Welcome to the forum.
There are several ways to accomplish this, but probably the easiest method, offering the greatest control (for a moving subject), is via Track Matte Keying.
One would create a Duplicate Clip, placing it on a higher Video Track, say Video Track 2, above the original Clip on Video Track 1. Then, a Blur Effect (Gaussian Blur works well) is applied to the Duplicate Clip on Video Track 2. Next, a Matte is created to hold out every area of that Blurred, Duplicate Clip, except for the face of the subject. This Matte can be created in Titler, or in a program, like Photoshop. It is placed on the next higher Video Track, say Video Track 3. Then, the Track Matte Keying is added to the Duplicate Clip, and linked to the Matte in Video Track 3. One can add Blur to that Matte, to soften the edges, if desired.
This article goes into more detail. Though it was written to show how to "highlight" a moving object, the mechanics are the same: http://forums.adobe.com/message/1765005#1765005
One can also use other Effects, such as Moasic, instead of Blur, if desired.
Good luck, and hope that this helps.
Merci pour votre réponse rapide.
cependant, étant néophyte, j'ai encore des questions:
- Qu'est ce que "track Matte Keying"
- existe il un didacticiel pour réaliser un floutage de visage? si oui,
pouvez-vous me l'envoyer?

The Track Matte Keying is one of the Keying Effects, offered in PrE.
