/hackness/liveness_hack_detect

1.接口描述

该API功能为检测用户拍摄的活体数据是否活人。

 

注1:此接口只能配合Android活体检测SDK或者iOS活体检测SDK使用;

注2:protobuf文件中包含加密的人脸图片、视频等活体数据,与移动端SDK设置参数OUTPUT_TYPE有关;

注3:文档中描述的“protobuf文件”、“加密文件”、“二进制文件”均为同一个意思。

 

请求方式

POST

请求 URL

https://cloudapi.linkface.cn/hackness/liveness_hack_detect

2.请求参数

字段 类型 必需 描述
api_id string API 账户
api_secret string API 密钥
liveness_data_file file 见下方注释 活体检测SDK返回的protobuf文件,上传本地文件进行检测时选取此参数
liveness_data_url string 见下方注释 活体检测SDK返回的protobuf文件的url,采用抓取网络文件方式时需选取此参数
liveness_data_id string 见下方注释 活体检测SDK返回的protobuf文件的id,在云端上传过文件可采用此参数

请求参数 liveness_data_file,liveness_data_urlliveness_data_id 三选一。

url 中含有不少特殊字符,若将 URL 放入 Query String 中则需要对这些字符进行转义,所有中文和特殊字符必需以UTF-8编码转义。 目前支持 http/https 等协议的网络地址。下载限时 5s,超时后仍未下载完成则属于失败。

> 备注:hack_score阈值为0.98,由行业大数据训练得到,大于0.98是hack行为,小于等于0.98是正常活人

3.返回参数

正常响应

字段 类型 说明
request_id string 本次请求的id
status string 状态,正常为 OK,其他值表示失败,详见错误码
score float 分数。取值范围是0~1。值越大,表示被hack的可能性越大
liveness_data_id string 使用file、url方式上传protobuff文件返回的云端protobuff文件的id

返回样例

{
  "request_id": "TID8bf47ab6eda64476973cc5f5b6ebf57e",
  "status": "OK",
  "score": "xxxxxx",
  "liveness_data_id": "xxxxxx"
}

4.错误码

状态码 status 字段 说明
400 ENCODING_ERROR 参数非UTF-8编码
400 DOWNLOAD_TIMEOUT 网络地址图片获取超时
400 DOWNLOAD_ERROR 网络地址图片获取失败
400 INVALID_ARGUMENT 请求参数错误,具体原因见 reason 字段内容
400 WRONG_LIVENESS_DATA liveness_data 出错
400 NO_FACE_DETECTED 图片未检测出人脸 ,详情见字段 image
401 UNAUTHORIZED 账号或密钥错误
401 KEY_EXPIRED 账号过期,具体情况见 reason 字段内容
403 RATE_LIMIT_EXCEEDED 调用频率超出限额
403 NO_PERMISSION 无调用权限
403 OUT_OF_QUOTA 调用次数超出限额
404 NOT_FOUND 请求路径错误
500 INTERNAL_ERROR 服务器内部错误

返回样例

{
    "status": "INVALID_ARGUMENT",
    "reason": "must specify 'liveness_data_file', 'liveness_data_url' or 'liveness_data_id' argument",
    "request_id": "TIDa892b593c0354b0e989b5db67a331607"
}
