Rest Jersey Automatic Base64 encoded Header parsing via Annotation

I am using jersey 1.9.1 I have rest method like following where Authorization header contained encoded credentials such as username and password and it is parsed in a method and mapped local values.

@PUT
@Path(SystemConstants.REST_MESSAGE_SENDSMS)
@Consumes(MediaType.APPLICATION_JSON)
@Produces({MediaType.APPLICATION_JSON})
public Response sendSms(@HeaderParam("Authorization") String authorization, String param) {

    String[] credentials = ImosUtils.getUserCredentials(authorization);
    String username = credentials[0];
    String password = credentials[1];       
    }

I am trying to design a way to make this process automatically, without writing same parsing code in each method. I mean I would like to know if writing a special annotation such as HeaderParamExtended to this is used to parse this credentials.
I am using jersey 1.9.1 version as rest api. Where I have to edit a class in that life cycle?

@PUT
@Path(SystemConstants.REST_MESSAGE_SENDSMS)
@Consumes(MediaType.APPLICATION_JSON)
@Produces({MediaType.APPLICATION_JSON})
public Response sendSms(@HeaderParamExtended("Authorization","username") String username, @HeaderParamExtended("Authorization","password") String password, , String param) {


    }
