Due to the swift development of cloud computing technology, an increasing number of healthcare organizations tend to store electronic health records (EHR) on cloud storage servers. To ensure patient privacy, sensitive information within EHR data must undergo encryption prior to being uploaded to the cloud server. Nonetheless, this encryption process alters the data's original structural characteristics, presenting a significant challenge in achieving effective and flexible EHR utilization, such as plaintext keyword search. Considering the privacy and practicality of EHR. This paper introduces a new cloud-based EHR system that integrates public-key encryption with the keyword search (PEKS) scheme. This system enables authorized users to conduct searches for specific keywords on encrypted EHR data, all while maintaining the highest level of data security. Compared to existing PEKS-based EHR system solutions, our approach is not limited by a secure channel, reducing communication overhead while taking full advantage of the large storage space and high computational performance of the cloud server to realize flexible and effective search capabilities. Furthermore, our solution effectively prevents online keyword guessing attacks from outside adversaries.

Text semantic similarity is a crucial research area in Natural Language Processing (NLP). However, traditional methods for calculating the similarity of short Chinese texts often fall short in accuracy and other crucial aspects. The Bidirectional Long Short-Term Memory Network (BiLSTM) has demonstrated remarkable performance in computing the similarity of short Chinese texts by effectively capturing long-range dependencies and semantic information. Additionally, the multi-head attention mechanism considers the interaction between different text locations and semantic information, enhancing the model’s representative capacity. Building upon this foundation, our paper proposes an enhanced model known as SCTbilstmAttRdrop (SCTAR). This model is constructed based on a multilayer BiLSTM architecture and incorporates an SE-gated convolutional module and a convolutional multi-head attention-aware model. We conducted extensive evaluations using two Chinese short text datasets, Chinese-SNLI and CCKS2018_Task3. The experimental results unequivocally demonstrate that our SCTAR model surpasses other common methods in terms of accuracy, precision, recall, and F1 scores when tasked with computing the similarity of Chinese short texts.

Image-text matching is an important task in cross-modal information processing, which consists of evaluating the similarity between images and text. However, the data of the two modalities have different distributions and representations, which cannot be directly compared. Therefore, the two modalities need to be processed separately. Most existing image-text matching methods extract image fragments and text fragments separately, using an attention mechanism to establish relationships between regions in the image and words in the text. Subsequently, they aggregate the similarity of these images and text fragments. Regardless, not all fragment alignment is meaningful, and irrelevant fragment alignment will bring redundancy and reduce retrieval accuracy. In addition to that, there are contextual relationships between image regions and between text words, which should also be taken into account. In this paper, we simultaneously consider these two aspects and propose a Semantic-Enhanced Attention Network (SEAN). It first focuses on each modality, mining contextual relationships between fragments within each modality and aggregating contextual information into visual and textual embeddings. Then, we compute the similarity between all image regions and text fragments, focusing all attention on the region-word pairs with the highest similarity. Finally, we summarize these to infer the similarity between the image and text. Our method achieves competitive results on two generalized image text retrieval datasets, Flickr30K and MS-COCO.
