Optionally, above-mentioned target can be, but not limited to include: to have in participant meeting-place with article to be encrypted in meeting meeting-place
The article of security classification can be the article of need for confidentiality in participant meeting-place in other words.Such as: classified document, secrecy books,
Secrecy certificate etc..
Through the above steps, the multimedia resource acquired from target and meeting meeting-place is obtained, and is obtained from the multimedia resource
The corresponding target resource of participant object to be encrypted is taken, target resource is encrypted according to the resource type of target resource, from
And make the corresponding part resource of participant object to be encrypted in multimedia resource carry out encryption, so that it is guaranteed that target with
Concerning security matters content in meeting meeting-place obtains secrecy processing, therefore, solves the multimedia resource secrecy effect transmitted in teleconference
Poor problem, and then improve the secrecy effect of the multimedia resource transmitted in teleconference.
Optionally, the target resource that is encrypted, available use are needed in order to extract from multimedia resource
In the default characteristic information for the feature that instruction participant object to be encrypted has, then match multimedia resource and default feature letter
Breath, obtains target resource.Such as: in above-mentioned steps S104, multimedia resource can be matched with default characteristic information,
Wherein, default characteristic information is used to indicate the feature that participant object to be encrypted has, and obtains in multimedia resource and default special
Reference ceases the resource of successful match, as target resource.
Optionally, for different participant objects can be different to its feature matched in multimedia resource.Example
Such as: multimedia resource can be matched with default characteristic information at least one in the following manner:
Mode one, by multimedia resource video resource and default characteristic information in the face feature information that carries carry out
Matching, wherein face feature information is used to indicate the facial characteristics of participant to be encrypted.
Mode two, by multimedia resource video resource and default characteristic information in the article characteristics information that carries carry out
Matching, wherein article characteristics information is used to indicate the feature of article to be encrypted.
Mode three, by multimedia resource audio resource and default characteristic information in the sound characteristic information that carries carry out
Matching, wherein sound characteristic information is used to indicate participant's sound characteristic to be encrypted.
Optionally, video resource can encrypt target resource using virtualization processing or mosaic processing, it is right
It can be using voice change process (such as: modified tone processing or frequency-conversion processing etc.) in audio resource.Such as: in above-mentioned steps S106
In, in the case where resource type includes video resource, obtain the display area of video resource on the video images；To viewing area
Domain carries out virtualization processing or mosaic processing；In the case where resource type includes audio resource, audio resource is become
Frequency processing or modified tone processing.
Optionally, the participant meeting-place for participating in teleconference may have one or more, their security classification may phase
Together, it is also possible to it is different, for example, some participant meeting-place maintain secrecy, participant meeting-place be not need to maintain secrecy
Processing, then can be determined according to the security classification in each participant meeting-place the target for needing to carry out above-mentioned encryption with
It can meeting-place.Such as: before above-mentioned steps S102, one or more available first security classification corresponding with meeting meeting-place
And the second security classification of teleconference, wherein one or more is the participant meeting-place for participating in teleconference with meeting meeting-place,
Security classification is used to indicate concerning security matters degree, and security classification is higher, and expression concerning security matters degree is bigger, protects to the first security classification with second
Level of confidentiality is not compared, obtains the participant meeting-place that the first security classification is higher than the second security classification, as target and meeting meeting-place.
Optionally, security classification can be, but not limited to be pre-set, such as: security classification may include: to need to protect
It is close and do not need secrecy two kinds, wherein need for confidentiality, which is superior to, does not need security classification, can indicate need for confidentiality with 1
Rank, use 0 indicate not needing the rank of secrecy.Security classification can also divide are as follows: top-secret, secret and secret, wherein top-secret
Security classification is higher than secret, and secret security classification is higher than secret, can indicate top-secret security classification with 2, use 1 indicates secret
Security classification, use 0 indicates secret security classification.
It is alternatively possible to determine teleconference according to one or more first security classification corresponding with meeting meeting-place
Second security classification.Such as: receive one or more and can the first security classification for sending of the conference terminal in meeting-place, by the
The minimum security classification of rank is determined as the second security classification of teleconference in one security classification.
In an optional embodiment, by taking security classification is divided into need for confidentiality and does not need secrecy as an example, Fig. 2 is
The schematic diagram of the security classification confirmation method of the teleconference of optional embodiment according to the present invention, as shown in Fig. 2, in meeting
Before beginning, each participant meeting-place determines participant's list, and transfers the data in respective confidential information library, determines each participant
The security classification of member.There are 3 participants and a meeting-place marker (being equivalent to the article in above-mentioned participant meeting-place) in meeting-place 1,
Wherein the security classification of participant 1A (201) is 0, i.e., without secrecy；The security classification of participant 1B (202) is 1, that is, is needed
It maintains secrecy；The security classification of participant 1C (203) is 0, i.e., without secrecy；First security classification in meeting-place 1 is 1 in this way
(204), the security classification of meeting-place marker 1D (204) is 1, i.e. need for confidentiality.
There are 3 participants in meeting-place 2, and wherein the security classification of participant 2A (206) is 1, i.e. need for confidentiality；Participant
The security classification of member 2B (207) is 1, i.e. need for confidentiality；The security classification of participant 2C (208) is 0, i.e., without secrecy；That
First security classification in meeting-place 2 is 1, i.e. need for confidentiality (209).
There are 3 participants in meeting-place 3, and wherein the security classification of participant 3A (210) is 0, i.e., without secrecy；Participant
The security classification of member 3B (211) is 1, i.e., without secrecy；The security classification of participant 3C (212) is 0, i.e., without secrecy；That
First security classification in meeting-place 3 is 0 (213).
To which according to the security classification in three participant meeting-place, the second security classification of this obtained teleconference is 0
(214)。
