One way is to set process variable when starting process instance.

This variable can be referenced in the tasks you want.

Map<String, Object> variableMap = new HashMap<String, Object>();
variableMap.put("initiator", "Activiti");
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("TestExtension", variableMap);
