An Effective Private Data storage and Retrieval System using Secret sharing scheme based on Secure Multi-party Computation

Privacy of the outsourced data is one of the major challenge.Insecurity of the network environment and untrustworthiness of the service providers are obstacles of making the database as a service.Collection and storage of personally identifiable information is a major privacy concern.On-line public databases and resources pose a significant risk to user privacy, since a malicious database owner may monitor user queries and infer useful information about the customer.The challenge in data privacy is to share data with third-party and at the same time securing the valuable information from unauthorized access and use by third party.A Private Information Retrieval(PIR) scheme allows a user to query database while hiding the identity of the data retrieved.The naive solution for confidentiality is to encrypt data before outsourcing.Query execution,key management and statistical inference are major challenges in this case.The proposed system suggests a mechanism for secure storage and retrieval of private data using the secret sharing technique.The idea is to develop a mechanism to store private information with a highly available storage provider which could be accessed from anywhere using queries while hiding the actual data values from the storage provider.The private information retrieval system is implemented using Secure Multi-party Computation(SMC) technique which is based on secret sharing. Multi-party Computation enable parties to compute some joint function over their private inputs.The query results are obtained by performing a secure computation on the shares owned by the different servers.Comment: Data Science & Engineering (ICDSE), 2014 International Conference, CUSA

A study of comparitive analysis of the outcome of Hardinge’s and Moore’s approach of hemi arthroplasty of hip

Background: The posterior (Moore) approach is generally considered to be easy to perform and has less tissue dissection, which leads to shorter operation times and less blood loss. The lateral (Hardinge) approach can provide generous exposure of the acetabulum, which facilitates cup positioning results may decrease rates of hip dislocation.Methods: In this study a prospective comparative study of outcome of Hardinge’s vs. Moore’s approach in hemi arthroplasty of hip done on 60 consecutive consenting cases who presented with a primary diagnosis of neck of femur fractures. The Selection of patients was randomized by selecting every alternate case of neck of femur fractures by Moore’s approach or Hardinge’s approach. Study recruited 30 cases in each group after the preoperative parameters like age, sex, side, mechanism of injury and the type of fracture.Results: 30 cases underwent hemi - arthroplasty of hip by Hardinge’s approach vs. Moore’s technique and we found that there was difference in duration of hospital stay, the duration of healing and the rate of complications were much higher in the Moore’s technique. In our study there was no mortality. Conclusions: Based on the findings of our study we recommend that between Hardinge’s and Moore’s approach, Hardinge’s approach is recommended as better than Moore’s approach due to number of complications is lower in Hardinge’s

Intra thyroid thyroglossal cyst: a rare presentation

Thyroglossal duct cyst is a congenital malformation occurring due to incomplete closure of the thyroglossal duct. The infrequency with which it is encountered in thyroid makes it a formidable diagnostic challenge. Authors report this case because of the rarity of intrathyroid location of thyroglossal cyst.

A study on the effect of adenoidectomy with tonsillectomy in otitis media with effusion in children

Background: The aural symptoms attributed to adenoid hypertrophy are Eustachian tube block (ET) and otitis media with effusion (OME). It is thought that adenoid hypertrophy causes a block in air flow through the ET, thus creating a negative pressure in the middle ear leading to effusion which acts as a focus of infection. The role of hypertrophied tonsils in the aetiology of OME is controversial. Adenoid and tonsillar hypertrophy and associated inflammation continue to be a major problem in paediatric age group despite the advances in medicine. Otitis media with effusion is a treatable cause of deafness which may hamper the learning ability of a child. This study was undertaken to study the effect of adenoidectomy with tonsillectomy on established otitis media with effusion in children.Methods: 35 children presenting to the department of ENT, Government Medical College, Thrissur, Kerala, India over one and a half years with features suggestive of secretory otitis media, tonsillar and adenoid hypertrophy who underwent adenoidectomy with tonsillectomy in Government Medical College, Thrissur, Kerala, India were included in the study. A predesigned questionnaire was prepared which included details on clinical symptoms, relevant investigations and preoperative and postoperative evaluation of hearing after 6 weeks and 3 months. Data collected was analyzed using paired t-test and chi square test to determine the improvement in hearing after 6 weeks and 3 months following surgery.Results: Out of the 35 children included in the study, it was seen that 56% of cases, after 6 weeks showed complete resolution of OME which improved to 67% after 3 months. This was assessed by PTA and tympanometry. 33% showed partial improvement with Type C curve in tympanometry and improvement in PTA values.Conclusions: All cases of OME associated with adenoid and tonsillar hypertrophy responded to our treatment with 67% showing complete cure of the condition. It can be assumed that, in the 33% partial responders there may be other factors like allergy, anatomical deformities, immunological which prevented the complete resolution of symptoms in OME.

Static traversable wormhole solutions in f(R,Lm)f(R,L_m) gravity

In this study, we explore the new wormhole solutions in the framework of new modified $f(R,L_m)$ gravity. To obtain a characteristic wormhole solution, we use anisotropic matter distribution and a specific form of energy density. As second adopt the isotropic case with a linear EoS relation as a general technique for the system and discuss several physical attributes of the system under the wormhole geometry. Detailed analytical and graphical discussion about the matter contents via energy conditions is discussed. In both cases, the shape function of wormhole geometry satisfies the required conditions. Several interesting points have evolved from the entire investigation along with the features of the exotic matter within the wormhole geometry. Finally, we have concluding remarks.Comment: Chinese Journal of Physics accepted versio

A rare case of extraovarian dysgerminoma in pregnancy

Extraovarian germ cell tumors are very rare and their occurrence in pregnancy is extremely rare. We presented a case of extraovarian dysgerminoma on the anterior abdominal wall in a G2P1L1, 34 weeks. It is challenging to manage such tumors, obstacles in the way namely are diagnosis as the presentation can be different from classical ovarian GCTs, limitations in the investigatory modalities in pregnancy, and management involving three independent entities-tumor, mother, fetus.
