Privacy and Security in Multi-modal User Interface Modeling for Social Media

  1. 1. Privacy  and  Security  in    Mul1-­‐modal  User  Interface  Modeling     for  Social  Media   Mohamed  Bourimi1,3,  Ricardo  Tesoriero2,  Pedro  G.   Villanueva2,  Fa<h  Karatas1,  Philipp  Schwarte1     1University  of  Siegen,  Chair  for  IT  Security,  Germany   2Compu1ng  Systems  Department.  University  of  Cas1lla-­‐La   Mancha,  Spain  3FernUniversität  in  Hagen,  Coopera1ve  Systems  Group,  Germany  
  2. 2. Overview  §  Background  and  Mo2va2on  §  Problem  Statement(s)  §  Requirements  Analysis  §  Proposed  Approach  §  Example  §  Eclipse  Security  Model  Editor  §  Future  Work  and  Conclusion  
  3. 3. Background  and  Mo2va2on  §  Interdisciplinary  research  becoming  more  important  in  the   area  of  Social  Media  (Modeling):   1.  Human-­‐Comupter  Interac2on  (HCI)  è  Usability   Engineering   2.  Groupware  and  Social  SoQware  è  Distributed  Systems   SoQware  Engineering  Suppor2ng  Collabora2on   3.  Privacy  and  Security  Engineering    §  Modeling  as  one  of  the  important  steps  in  the  SoQware   Engineering  Process  could  help  in  considering  the   requirements  :   •  Early  Enforcement  (Bourimi  et  al.  AFFINE     methodology,  HCSE2010)   •  Adequately  by  considering  social  factors,  too!   (which  is  not  part    of  other  business  domains)  
  4. 4. Abuses,  risks  and  threats  when  using  Social  Media!  §  Scandals  are  becoming  ordinary  (due  to     accidental  or/and  inten2onal  abuses)  with     fatal  consequences  in  some  situa2ons!!  §  Iden2fica2on  remains  possible  with  an  error     rate  of  just  12%  (Narayanan&Shama2kov     2009)    §  Many  other  examples  for  loosing  privacy  and     evolving  risks  and  threats  ..  
  5. 5. Problem  Statement(s)  §  General  problem  statement:  Improving  the   modeling  of  systems  suppor<ng  social  interac<on  in   general  (considering  all  involved  research  fields   togetherè  Targe<ng  Synergy  Effect)  §  Specific  problem  statement  (here):  Using   standard(s)  for  efficient  support  of  generated  user   interfaces  by  considering  mul<-­‐modality  (Web,   Mobile,  Desktop  etc.)  when  using  social  media   systems  (e.g.,  for  evalua<on  based  research,   frequent  provision/adap<on  of  prototypes  is   needed!)  
  6. 6. Requirements  Analysis:  „SocialTV  Case  Study“  §  “Perfect  Labor”  in  our  case:  SocialTV  interdisciplinary   project  running  since  2009  (presented  @SocialCom   2010)  èhQp://www.uni-­‐siegen.de/T5/itsec/forschung/projekte/socialtv.html  
  7. 7. Requirements  Analysis:  Further  Gathered  Requirements  §  R1:    Reflec2ng  realis2c  SocialTV  situa2ons  (individual   and  group  interac2ons)  §  R2:    Allowing  for  flexible  parallel  interac2on  of  the   involved  people  §  R3:    Flexibility  in  terms  of  costs  emerging  from   adapta2ons  to  new  situa2ons  and  tests  §  R4:    Suppor2ng  thereby  secure  and  privacy-­‐ preserving  interac2on  
  8. 8. Approach  §  Approach  is  based  on  same  technologies  we  use   for  development  of  context-­‐aware  applica2ons  for   ubiquitous  compu2ng  environments  using  the   Model-­‐Driven  Architecture  (MDA):   •  Metamodling  and  UsiXML     (Cameleon  Reference  Framework)   •  Eclipse   •  For  Security/Privacy  è  Security     Metamodel  (next  slide)      
  9. 9. Approach  §  For  Security/Privacy  è  Metamodel   oriented  to  PriS  (2008):   - Principals  (user  model)   - Resources  (domain     model)   - Ac2vi2es  (task  model)      
  10. 10. Solu2on  sa2sfying  our  requirements  (R1-­‐R4)  
  11. 11. Approach:  Security  Metamodel  and  DSL  
  12. 12. Example  Security model
  13. 13. Current  State:  Security  Modeling  Editor  §  Developed  using  the  Eclipse  plahorm  as  a  plugin   •  EMF     •  GMF  §  As  consequence   •  Metamodels  in  ECORE  format   •  Models  in  XMI  (OMG  standard  for  model  representa2ons)  §  Main  Advantage   •  Genera2on  of  a  plahorm  independent  security  models  §  OCL  Model  Valida2on  (i.e.  Aiributes)  §  MOFScript  (Model  2  Text  transforma2on)  
  14. 14. First  Results  (Modeling)  §  In  total,  we  conducted  interviews,  walkthroughs  and   collected  first  usage  experiences  of  the  current  modeling   framework  (including  the  first  primi2ve  version  of  the   Security  Metamodeling  Eclipse-­‐based  Editor)  with  21   par2cipants  from  the  educa2onal  and  industrial  field  §  We  are  currently  suppor2ng  various  widgets  such  as    fields   for  entering  different  data  (e.g.,  username  and  password),   combo  boxes,  etc.  (Official  Status  will  be  announced  this   week  in  a  presenta2on  for  OMG)    
  15. 15. Experiences  (for  Current  Status)  §  Requirements  resulted/s2ll  resul2ng  mainly  from   interdisciplinary  research  projects  è  Students  and   researchers  working  together  in  academic  evalua2on!      §  We  received  wishes  for  improvements  from  industrial   contacts  and  partners  in  other  projects  è  Interac2ve  TV   por2ng  (s2ll  needing  access  to  special  HW  suppor2ng  our   technologies  such  as  TVs  suppor2ng  HTML5  or  Android   Plahorm)  
  16. 16. Future  work  and  conclusion  §  Future  work  is  primarily  focused  on:   •  Improving  the  Security  Metamodel  by  adding  itera2vely   further  security  and  privacy  requirements!   •  Improving  the  used  Security  Metamodling  Editor  for   easing  the  modeling  of  related  design/modeling/ development  tasks  §  This  needs  improving  the  underlying  UsiXML  framework   which  is  in  evolu2on  for  the  moment  for  mee2ng  standards   (OMG  /  W3C  proposals  submiied!)
